Sebelum kita mencoba mengingat rumus-rumus integral triogonometri maka sebaiknya kita ingat dulu turunan trigonometri. Turunan trigonometri bisa kita tuliskan sebagai berikut&lt;br /&gt;y = sin x maka y' = cos x&lt;br /&gt;y = cos x maka y' = - sin x&lt;br /&gt;y = tan x maka y' = sec&lt;sup&gt;2&lt;/sup&gt; x&lt;br /&gt;y = cot x maka y' = -csc&lt;sup&gt;2&lt;/sup&gt; x&lt;br /&gt;y = sec x maka y' = sec x tan x&lt;br /&gt;y = csc x maka y' = -csc x cot x&lt;br /&gt;&lt;br /&gt;Dengan demikian jika rumus-rumus ini kita balik akan menjadi&lt;br /&gt;&lt;a href="http://www.codecogs.com/eqnedit.php?latex=%5Cint%20cos%20x%20dx%20=%20sin%20x%20@plus;%20c" target="_blank"&gt;&lt;img

Sebutan tri dikarenakan ada tiga macam perbandingan pada sisi-sisi segitiga siku-siku. Nilai hasil perbandingan ini tentunya dipengaruhi oleh sudut-sudut pada segitiga siku-siku tersebut. Jadi bisa dikatakan, ini merupakan pemetaan dari nilai sudut menuju kepada perbandingan sisi-sisi segitiga. Karena berupa pemetaan maka seringkali disebut fungsi trigonometri. Ketiga perbandingan tersebut adalah sinus, cosinus dan tangen. Akan tetapi dalam perkembangannya ketiga perbandingan tersebut seringkali dibalik sehingga disebut secan, cosecant dan cotangen.&lt;br /&gt;&lt;br /&gt;Ketiga sisi dalamsegitiga siku-siku seringkali disebut sisi miring, sisi depan dan sisi samping. Sisi miring merupakas sisi terpanjang dari segitiga siku-siku, atau sisi yang berada di depan segitiga siku-siku. Sisi yang lain selain sisi miring sering disebut sisi siku-siku. Untuk membedakan kedua sisi maka seringkali diberi nama sisi depan dan sisi samping. Sisi depan merupakan sisi yang berada di depan sudut yang akan kita hitung nilai fungsi trigonometrinya. Sisi samping merupakan sisi siku-siku yang berada di samping sudut yang akan kita hitung nilai fungsi trigonometrinya.&lt;br /&gt;&lt;br /&gt;Sinus merupakan hasil perbandingan sisi depan dengan sisi miring, sedangkan cosinus merupakana perbandingan sisi samping dengan sisi miring. Tangen agak berbeda dengan keduanya karena tidak melibatkan sisi miring. Tangen merupakan perbandingan sisi depan dengan sisi samping.&lt;br /&gt;&lt;br /&gt;untuk mempermudah mengingatnya maka seringkali ditulis&lt;br /&gt;sinus : de-mi (perbadingan sisi &lt;span style="font-weight: bold;"&gt;de&lt;/span&gt;pan dengan sisi &lt;span style="font-weight: bold;"&gt;mi&lt;/span&gt;ring)&lt;br /&gt;cosinus : sa-mi (perbandingan sisi &lt;span style="font-weight: bold;"&gt;sa&lt;/span&gt;mping dengan sisi &lt;span style="font-weight: bold;"&gt;mi&lt;/span&gt;ring)&lt;br /&gt;tangen : de-sa (perbandingan sisi &lt;span style="font-weight: bold;"&gt;de&lt;/span&gt;pan dengan &lt;span style="font-weight: bold;"&gt;sa&lt;/span&gt;mping)&lt;br /&gt;&lt;br /&gt;Untuk lebih jelasnya perhatikan gambar berikut:&lt;br /&gt;&lt;br /&gt;&lt;a

Metode Matriks adalah suatu metode relatif memiliki lang­kah-langkah pengerjaan yang cukup sederhana untuk mencari solusi partikulir. Metode ini dikembang­kan dengan menggunakan konsep-konsep dasar Mat­riks, linearitas, identitas Euler, dan sifat-sifat solusi PD.&lt;/div&gt;&lt;div class="paragrafjurnal"&gt;Tujuan telaahan dalam tulisan ini adalah untuk menghasilkan suatu ru­mus atau formula solusi pertikulir yang lebih umum untuk PD linear tak ho­mogen dengan koe­fisien konstanta yang diturunkan dari metode Koefisien Tak Tentu. Kemudian, solusi partikulir yang diperoleh dengan metode Matriks ini dibandingkan dengan hasil solusi partikulir yang diperoleh dengan meng­gunakan metode Koefisien Tak Tentu. Untuk men­capai hal ini, digunakan be­berapa contoh.&lt;/div&gt;&lt;div class="paragrafjurnal"&gt;Batasan-batasan&lt;span&gt;&amp;nbsp; &lt;/span&gt;telaahan ini adalah PD Linear Orde Dua Tak Homogen dengan Koefisien Konstanta:&lt;/div&gt;&lt;div class="MsoNormal" style="margin-left: 85.05pt;"&gt;&lt;sub&gt;&lt;img height="41" src="http://pk.ut.ac.id/jmst/v1n1/zulmahdi_files/image008.gif" width="132" /&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;(1)&lt;/div&gt;&lt;div class="MsoNormal" style="text-align: justify;"&gt;di mana &lt;i&gt;p&lt;/i&gt;, &lt;i&gt;q&lt;/i&gt; konstanta, dan &lt;sub&gt;&lt;img height="23" src="http://pk.ut.ac.id/jmst/v1n1/zulmahdi_files/image010.gif" width="88" /&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;dengan &lt;sub&gt;&lt;img height="19" src="http://pk.ut.ac.id/jmst/v1n1/zulmahdi_files/image012.gif" width="40" /&gt;&lt;/sub&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;(&lt;i&gt;bilangan kompleks&lt;/i&gt;) dan&lt;/div&gt;&lt;div class="MsoNormal" style="margin-left: 85.05pt;"&gt;&lt;sub&gt;&lt;img height="43" src="http://pk.ut.ac.id/jmst/v1n1/zulmahdi_files/image014.gif" width="212" /&gt;&lt;/sub&gt;.&lt;span&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; &lt;/span&gt;(2)&lt;/div&gt;&lt;div class="subheadingjurnal" style="margin-top: 12pt;"&gt;KONSEP PENDUKUNG&lt;/div&gt;&lt;div class="paragrafjurnal"&gt;Metode-metode&lt;span&gt;&amp;nbsp; &lt;/span&gt;yang&lt;span&gt;&amp;nbsp; &lt;/span&gt;sudah&lt;span&gt;&amp;nbsp; &lt;/span&gt;sangat&lt;span&gt;&amp;nbsp; &lt;/span&gt;dikenal&lt;span&gt;&amp;nbsp; &lt;/span&gt;dalam&lt;span&gt;&amp;nbsp; &lt;/span&gt;penentuan solusi partikulir untuk PD Linear Orde Dua Tak Homogen dengan Koefisien Kon­stanta, antara lain, adalah metode &lt;i&gt;Transformasi Laplace&lt;/i&gt;, &lt;i&gt;Variasi Parameter, &lt;/i&gt;dan &lt;i&gt;Koefisien Tak Tentu&lt;/i&gt;.

&lt;/span&gt;Solusi PD homogen tidak diperlukan, dan Akar-akar karakteristik PD ho­mogen ti­dak dibutuh­kan secara lengkap, tetapi hanya menurunkan/ mendiferensialkan bentuk pada persamaan (10) secara sederhana sebanyak&lt;span&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;

&lt;/span&gt;Sistematika pengerjaan mencari solusi lebih sederhana, karena da­lam pengerjaan tinggal mensubstitusi parameter-parameter yang diketahui kedalam bentuk rumus umum dan juga tidak berhubungan dengan kon­stanta tak diketahui seperti pada me­tode Koefisien Tak Tentu dan Variasi Parameter.&lt;span&gt;&amp;nbsp;

Tidak pernah terbayangkan oleh manusia sebelumnya, sampai  ditemukan bahwa bilangan prima juga merupakan dasar dari kehidupan  alam, yang dengan usaha keras ingin dijelaskan oleh ilmu ini dalam  sains. Pandangan orang umumnya mengatakan bahwa matematika hanyalah  penemuan manusia biasa. Sebaliknya, beberapa pemikir masa lalu -  Pythagoras, Plato, Cusanus, Kepler, Leibnitz, Newton, Euler, Gauss,  termasuk para revolusioner abad ke-20, Planck, Einstein dan Sommerffeld -  yakin bahwa keberadaan angka dan bentuk geometris merupakan konsep alam  semesta dan konsep yang bebas (&lt;span style="font-style: italic;"&gt;independent&lt;/span&gt;). Galileo sendiri beranggapan bahwa matematika adalah bahasa Tuhan ketika menulis alam semesta. &lt;br /&gt;&lt;br /&gt;&lt;a name='more'&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;h3&gt;Bilangan Prima dan Rencana Penciptaan&lt;/h3&gt;&lt;br /&gt;Salah satu teka-teki lama yang belum sepenuhnya terpecahkan adalah bilangan prima. &lt;span style="font-weight: bold;"&gt;Bilangan prima&lt;/span&gt;  adalah bilangan yang hanya dapat habis dibagi oleh bilangan itu sendiri  dan angka 1. Angka 12 bukan merupakan bilangan prima, karena dapat  habis dibagi oleh angka lainnya 2, 3, dan 4. Bilangan prima adalah 2, 3,  5, 7, 11, 13, .... dan seterusnya. Banyak bilangan prima tidak  terhingga. Tidak peduli berapa banyak kita menghitung, pasti kita akan  menemukan bilangan prima, walaupun mungkin makin jarang_ Hal ini menjadi  teka-teki kita, jika kita ingat bilangan ini tidak dapat dibagi oleh  angka lainnya. Salah satu hal yang menakjubkan, dalam era komputer kita  memberikan kodetifikasi semua hal yang penting dan rahasia, di bank,  asuransi, dan perhitungan-perhitungan peluru kendali, &lt;span style="font-style: italic;"&gt;security system&lt;/span&gt;  dengan enkripsi, dalam angka jutaan bilangan-bilangan yang tidak habis  dibagi oleh angka lainnya. Ini diperlukan karena dengan penggunaan angka  lain, kodetifikasi tadi dapat dengan mudah ditembus.&lt;br /&gt;&lt;br /&gt;Fenomena inilah yang ditemukan ilmuwan dari Duesseldorf (Dr. Plichta),  sehubungan dengan penciptaan alam, yaitu distribusi misterius bilangan  prima. Para ilmuwan sudah lama percaya bahwa bilangan prima adalah  bahasa universal yang dapat dimengerti oleh semua makhluk (spesies)  berintelegensia tinggi, sebagai komunikasi dasar antarmereka. Bahasa ini  penuh misteri karena berhubungan dengan perencanaan universal kosmos.&lt;br /&gt;&lt;br /&gt;Bilangan lain yang perlu diketahui adalah sisa dari bilangan prima, yakni &lt;span style="font-weight: bold;"&gt;bilangan komposit&lt;/span&gt;,  kecuali angka 1, yaitu 4, 6, 8, 9,10,12,14,15, .... dan seterusnya.  Dengan kata lain, bilangan komposit adalah bilangan yang terdiri dari  minimal dua faktor prima. Misalnya : &lt;br /&gt;&lt;br /&gt;6 = 2 x 3 = 2 . 3&lt;br /&gt;30 = 2 x 3 x 5 = 2 . 3 . 5&lt;br /&gt;85 = 5 x 17 = 5 . 17&lt;br /&gt;&lt;br /&gt;Selain itu, dikenal pula &lt;span style="font-weight: bold;"&gt;bilangan khusus&lt;/span&gt;, yang disebut &lt;span style="font-weight: bold;"&gt;prima kembar&lt;/span&gt;, yaitu bilangan prima yang angkanya berdekatan dengan selisih 2. Misalnya : &lt;br /&gt;&lt;br /&gt;(3,5)&lt;br /&gt;(5,7)&lt;br /&gt;(11,13)&lt;br /&gt;(17,19)&lt;br /&gt;&lt;br /&gt;dan seterusnya.&lt;br /&gt;&lt;br /&gt;Mayoritas ahli astrofisika juga percaya bahwa di alam semesta terdapat&amp;nbsp; "kode kosmos"&amp;nbsp; atau yang disebut &lt;span style="font-style: italic;"&gt;cosmic code based on this order,&lt;/span&gt;&amp;nbsp; yang dikenal juga sebagai &lt;span style="font-style: italic;"&gt;Theory of Everything&lt;/span&gt;  (TOE), yang artinya terdapat konstanta-konstanta alam semesta yang  saling berhubungan berdasarkan perintah pendesain. Sekali perintah  tersebut dapat dipecahkan, maka hal ini akan membuka pandangan sains  lainnya yang berhubungan.&lt;br /&gt;&lt;br /&gt;Sumber : &lt;a href="http://www.forumsains.com/artikel/matematika-dan-bilangan-prima%20/"&gt;http://www.forumsains.com/artikel/matematika-dan-bilangan-prima%20/&lt;/a&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-7538605788145498503?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/7538605788145498503/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=7538605788145498503&amp;isPopup=true' title='0 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/7538605788145498503'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/7538605788145498503'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2011/08/matematika-dan-bilangan-prima.html' title='Matematika dan Bilangan Prima'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-2720354381343151621</id><published>2011-07-19T21:07:00.000-07:00</published><updated>2011-07-19T21:09:02.033-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='PR Checker'/><category scheme='http://www.blogger.com/atom/ns#' term='Article'/><title type='text'>I do not believe My Blog have PR 2</title><content type='html'>&lt;a href="http://www.kurnia25.blogspot.com/"&gt;www.kurnia25.blogspot.com&lt;/a&gt;, is a blog that has not been my care. But, this blog turned out to have rank 2. Which makes me wonder is, I rarely update the posts on this blog. Total posts there are also 75 pieces only. So I think about what is causing this blog has a PR 2?&lt;br /&gt;&lt;br /&gt;Quote I saw again all the posts that exist. Almost all of them are my original writings. Although discussed it messy, the number of words in one post sometimes less than 200 words. But of all posts is much like it.&lt;br /&gt;&lt;br /&gt;From this I concluded, why &lt;a href="http://www.kurnia25.blogspot.com/"&gt;www.kurnia25.blogspot.com&lt;/a&gt; has PR 2. Since posting the original article and useful. Hopefully I can continue to keep writing articles that original, unique and useful to the visitors &lt;a href="http://www.kurnia25.blogspot.com/"&gt;www.kurnia25.blogspot.com&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;To check my blog PR , please visit &lt;a href="http://www.prchecker.info/"&gt;http://www.prchecker.info/&lt;/a&gt;. then entry my url and check.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;script src="http://adsensecamp.com/show/?id=PwoCyRbtDcs%3D&amp;amp;cid=Jw0%2BaU5zMLg%3D&amp;amp;chan=BTZecPhvWEQ%3D&amp;amp;type=12&amp;amp;title=3D81EE&amp;amp;text=000000&amp;amp;background=FFFFFF&amp;amp;border=000000&amp;amp;url=2BA94F" type="text/javascript"&gt;&lt;/script&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;script src="http://adsensecamp.com/show/?id=PwoCyRbtDcs%3D&amp;amp;cid=Jw0%2BaU5zMLg%3D&amp;amp;chan=BTZecPhvWEQ%3D&amp;amp;type=5&amp;amp;title=3D81EE&amp;amp;text=000000&amp;amp;background=FFFFFF&amp;amp;border=000000&amp;amp;url=2BA94F" type="text/javascript"&gt;&lt;/script&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-2720354381343151621?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/2720354381343151621/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=2720354381343151621&amp;isPopup=true' title='1 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/2720354381343151621'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/2720354381343151621'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2011/07/i-do-not-believe-my-blog-have-pr-2.html' title='I do not believe My Blog have PR 2'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-7928176627776294846</id><published>2011-05-27T10:26:00.000-07:00</published><updated>2011-05-27T10:26:09.223-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='journal'/><title type='text'>Collection of the International Mathematical Journal (Kumpulan Jurnal Matematika Internasional)</title><content type='html'>Here is a collection of international &lt;a href="http://www.amazon.com/JUMP-Understanding-Mathematical-Principles-Teachers/dp/0615454445?ie=UTF8&amp;amp;tag=mathesblog-20&amp;amp;link_code=btl&amp;amp;camp=213689&amp;amp;creative=392969" target="_blank"&gt;mathematical journals&lt;/a&gt;&lt;img alt="" border="0" height="1" src="http://www.assoc-amazon.com/e/ir?t=mathesblog-20&amp;amp;l=btl&amp;amp;camp=213689&amp;amp;creative=392969&amp;amp;o=1&amp;amp;a=0615454445" style="border: none !important; margin: 0px !important; padding: 0px !important;" width="1" /&gt;.

Dan yang lebih mengenaskan lagi PBB yang katanya organisasi Dunia pun diam saja. Bahkan ketika salah satu Supir truk pengangkut bantuan kemanusiaan dari PBB tewas, PBB diam saja seolah-olah takut dengan Israel.&lt;br /&gt;&lt;br /&gt;Buat saudara-saudaraku di Palestina, doa kami tak pernah surut walaupun raga kami belum diperbolehkan untuk ikut berjihad di bumi Al_aqsa.&lt;br /&gt;&lt;br /&gt;Dan menurut saya pribadi, sebetulnya Israel sedang panik dan khawatir dengan akan "Lengsernya" George Bush pada tanggal 20 Januari 2009 nanti. Sehingga mereka memanfaatkan waktu yang masih tersisa untuk membumihanguskan palestina. Jadi, Insya Allah selepas pelantikan B. Obama sebagai presiden Amerika. Israel akan kehilangan dukungan terbesarnya "Bush laknatullah".&lt;br /&gt;&lt;br /&gt;&lt;script src="http://kumpulblogger.com/scahor.php?b=128&amp;amp;onlytitle=1" type="text/javascript"&gt;&lt;/script&gt;&lt;br /&gt;Bagi saudara-saudara muslim dunia.

Memenangkan sebuah peperangan bukan cuma dengan jumlah prajurit yang banyak, tapi dengan strategi perang yang matang. Salah satu strategi perang Tsun Tzu yang sangat menarik buatku adalah strategi "diam" (aslinya strategi kota kosong). &lt;br /&gt;&lt;br /&gt;Dari strategi kota kosong ini, dapat saya tarik pelajaran bahwa "diam"bukan berarti tak bertindak. Tapi justru dengan diam, kita bisa menganalisis pergerakan musuh dengan matang. Musuhpun akan bingung untuk bergerak. &lt;br /&gt;&lt;br /&gt;Mungkin banyak orang yang stelah lulus kuliah langsung dapat kerja, langsung bisa buka usaha. Tapi untuk orang-orang yang stelah lulus susah mendapat kerjaan, buka usahapun susah (seperti saya ;-)). Maka sudah saatnya kita "diam"untuk atur nafas dan strategi yang akan kita jalankan.&lt;br /&gt;&lt;br /&gt;Jangan sampai gara-gara ga dapat kerja &amp;amp; susah buka usaha, kita sampai memfonis diri kita sebagai orang yg gagal. Walapun untuk slalu berpikir optimis membutuhkan kerja keras yang tidak mudah, mungkin lebih berat ketimbang mengangkat batu 1 kg, he... 3x. Aku teringat dengan sebuah pepatah arab "Man jadda Wa jada" barang siapa bersungguh-sungguh, maka akan memperoleh apa yg diusahakan (terjemah bebas).&lt;br /&gt;&lt;br /&gt;Mungkin sedikit tulisan ini bisa bermanfaat bagi saya sendiri dan juga bagi smua pengunjung blog ini.&lt;br /&gt;kurnia25 disudut jogja&lt;br /&gt;saidin21 disudut brebes&lt;br /&gt;&lt;br /&gt;Tetap smangat...&lt;br /&gt;&lt;br /&gt;&lt;script src="http://kumpulblogger.com/sca.php?b=128" type="text/javascript"&gt;&lt;/script&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-2442449430392106854?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/2442449430392106854/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=2442449430392106854&amp;isPopup=true' title='0 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/2442449430392106854'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/2442449430392106854'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2008/09/atur-strategi-diam-bukan-berarti-tak.html' title='Atur strategi, diam bukan berarti tak bertindak.'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-7310677451257626109</id><published>2008-09-10T19:55:00.001-07:00</published><updated>2011-03-16T19:56:12.078-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Artikel'/><title type='text'>Blogging lewat HP (Handphone)</title><content type='html'>Blogging lewat HP?

Karena yang memberikan kehidupan adalah Allah SWT.&lt;br /&gt;&lt;br /&gt;Kalo kita mau menengok sejarah Matematika, maka banyak orang2 yang besar dari Matematika. Tapi mereka kebanyakan bukan mencari hidup dan ketenaran dari Matematika. Tapi mereka adalah orang2 yang besar Karena ingin Memperluas dan memperdalam Ilmu Matematika Mereka.&lt;br /&gt;&lt;br /&gt;Trus... apa kaitannya matematika dengan kehidupan????&lt;br /&gt;&lt;br /&gt;Banyak.... klo kita perhatikan, ga usah dengan seksama. Tapi Sepintas aja sudah cukup. Kita lihat dan mungkin kita menjalaninya setiap hari. Tapi masih banyak orang yang tidak sadar.&lt;br /&gt;&lt;br /&gt;Kita setiap hari selalu bergubungan dengan yang namanya jual beli. ada penjual dan ada pembeli. Dan dalam jual beli itu, kita secara sadar atau tidak sedang menerapkan ilmu matematika. Dan kalau ditelusuri lebih lanjut.

Tapi untuk memperolehnya dibutuhkan kerja keras dan selalu bertawakkal kepada yang mempunyai dan mengatur rezeki. &lt;/div&gt;&lt;div align="justify"&gt;Tadi malam saya sempat kedatangan seorang (mohon maaf) Pengamen yang mau menukarkan uang hasil Ngamennya. Ya, berhubung setiap hari saya membutuhkan uang recehan yang tidak sedikit, jadi saya trima pengamen tadi dengan baik2. &lt;/div&gt;&lt;div align="justify"&gt;Pengamen tadi tak suruh menghitung dulu uang yang mo ditukarkan. Tapi beliaunya ga mau menghitungnya sendiri. Jadi kami bertiga (saya, temen saya &amp;amp; pengamen) sama2 menghitungnya. Pertama, pengamen tadi mengeluarkan uang recehan (200 &amp;amp; 500 rupiah). Kami kemudian menghitungnya, dan hasilnya yaitu 25 ribu. Kami kira sudah tidak ada. Tapi ternyata si pengamen tadi masih punya uang recehan.&lt;/div&gt;&lt;div align="justify"&gt;Si pengamen mengeluarkan uang recehan yang kedua, jumlahnya hampir sama dengan yang pertama. Kami pun menghitungnya lagi, dan jumlahnya sama 25 ribu. Belum selesai kami menghitung yang kedua, bapaknya masih mengeluarkan uang receh lagi. Dan total uang recehan (campuran 100, 200 dan 500 rupiah) yang diperoleh oleh si pengamen tadi adalah Rp.75.000. &lt;/div&gt;&lt;div align="justify"&gt;Sebenarnya si pengamen tadi juga mau menukarkan uang receh Rp.1000, tapi berhubung uang ribuan kami masih banyak. Maka kami tidak menerimanya. Uang ribuan yang mau ditukarkan jumlannya sekitar 25 ribuan. &lt;/div&gt;&lt;div align="justify"&gt;Setelah capek hitung-hitungan uang. Akhirnya saya menyerahkan uang Rp. 75.000 (50an, 20an &amp;amp; 5 ribuan). Trus tiba2 temenku bilang gini sama si pengamen " Wah... bisa cepet kaya nih pak klo penghasilannya setiap hari hampir 90 ribu????? ". Hee... kalo dipikir2 memang bener. Saya pun jadi berfikir, pantesan sekarang banyak orang yang mau berprofesi jadi "PENGAMEN". Habis penghasilannya melebihi gaji guru yang hanya beberapa puluh ribu saja perhari. &lt;/div&gt;&lt;div align="justify"&gt;Tapi.... bayangkan. Gaji guru yang tidak seberapa besar tapi diperoleh dengan cara yang halal (bukan berarti ngamen tidak halal) akan lebih barokah dibandingkan dengan hasil Ngamen. So.... jangan ikut2an ngamen yach. Ayo kita budayakan wiraswasta dan entrepreneurship. &lt;/div&gt;&lt;div align="justify"&gt;Salam sukses..&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;script src="http://kumpulblogger.com/scahor.php?b=128&amp;amp;onlytitle=1" type="text/javascript"&gt;&lt;/script&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-5208831478058991160?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/5208831478058991160/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=5208831478058991160&amp;isPopup=true' title='1 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/5208831478058991160'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/5208831478058991160'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2008/05/penghasilan-pengamen-rp90000-hari-10.html' title='Penghasilan pengamen Rp.90.000 / hari (+/- $ 10 )'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>1</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-234218315031510136</id><published>2008-04-29T13:02:00.000-07:00</published><updated>2011-03-16T19:57:17.595-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='artikel islam'/><category scheme='http://www.blogger.com/atom/ns#' term='Article'/><title type='text'>Matematika Dulu, Sekarang dan yang Akan Datang</title><content type='html'>&lt;div align="justify"&gt;Kalo melihat perkembangan sejarah matematika.

At this time, &lt;a href="http://en.wikipedia.org/wiki/Polygamy" title="Polygamy"&gt;polygamy&lt;/a&gt; was a common practice among the &lt;a href="http://en.wikipedia.org/wiki/Nobility" title="Nobility"&gt;nobility&lt;/a&gt;.&lt;/div&gt;&lt;div align="justify"&gt;Kartini's father, RMAA Sosroningrat, was originally the district chief of Mayong. Her mother was MA Ngasirah, the daughter of Kyai Haji Madirono, a teacher of religion in Teluwakur, Jepara, and Nyai Haji Siti Aminah. At that time, colonial regulations specified that a Regency Chief must marry a member of the nobility and because MA Ngasirah was not of sufficiently high nobility&lt;a href="http://en.wikipedia.org/wiki/Kartini#cite_note-0" title=""&gt;[1]&lt;/a&gt;, her father married a second time to Raden Ajeng Woerjan (Moerjam), a direct descendant of the &lt;a href="http://en.wikipedia.org/wiki/Raja" title="Raja"&gt;Raja&lt;/a&gt; of &lt;a class="mw-redirect" href="http://en.wikipedia.org/wiki/Madura" title="Madura"&gt;Madura&lt;/a&gt;. After this second marriage, Kartini's father was elevated to Regency Chief of Jepara, replacing his second wife's own father, RAA Tjitrowikromo.&lt;/div&gt;&lt;div align="justify"&gt;Kartini was the fifth child and eldest daughter in a family of eleven, including half siblings. She was born into a family with a strong intellectual tradition. Her grandfather, Pangeran Ario Tjondronegoro IV, became a Regency Chief at the age of 25 while Kartini's older brother Sosrokartono was an accomplished &lt;a href="http://en.wikipedia.org/wiki/Linguistics" title="Linguistics"&gt;linguist&lt;/a&gt;.&lt;/div&gt;&lt;div align="justify"&gt;Kartini's family allowed her to attend school until she was 12 years old. Here, among other subjects, she learnt to speak fluent &lt;a href="http://en.wikipedia.org/wiki/Dutch_language" title="Dutch language"&gt;Dutch&lt;/a&gt;, an unusual accomplishment for Javanese women at the time&lt;a href="http://en.wikipedia.org/wiki/Kartini#cite_note-1" title=""&gt;[2]&lt;/a&gt;. After she turned 12 she was 'secluded' at home, a common practice among Javanese nobility, to prepare young girls for their marriage. During seclusion girls were was not allowed to leave their parents' house until they were married, at which point authority over them was transferred to their husbands. Kartini's father was more lenient than some during his daughter's seclusion, giving her such privileges as &lt;a href="http://en.wikipedia.org/wiki/Embroidery" title="Embroidery"&gt;embroidery&lt;/a&gt; lessons and occasional appearances in public for special events.&lt;/div&gt;&lt;div align="justify"&gt;During her seclusion, Kartini continued to educate herself on her own. Because Kartini could speak Dutch, she acquired several Dutch &lt;a href="http://en.wikipedia.org/wiki/Pen_pal" title="Pen pal"&gt;pen friends&lt;/a&gt;. One of them, a girl by the name of &lt;a class="new" href="http://en.wikipedia.org/w/index.php?title=Rosa_Abendanon&amp;amp;action=edit&amp;amp;redlink=1" title="Rosa Abendanon (page does not exist)"&gt;Rosa Abendanon&lt;/a&gt;, became her very close friend. Books, newspapers and European magazines fed Kartini's interest in &lt;a href="http://en.wikipedia.org/wiki/Europe" title="Europe"&gt;European&lt;/a&gt; &lt;a href="http://en.wikipedia.org/wiki/Feminism" title="Feminism"&gt;feminist thinking&lt;/a&gt;, and fostered the desire to improve the conditions of indigenous women, who at that time had a very low social status.&lt;/div&gt;&lt;div align="justify"&gt;Kartini's omnivorous reading included the &lt;a href="http://en.wikipedia.org/wiki/Semarang" title="Semarang"&gt;Semarang&lt;/a&gt; newspaper De locomotief, edited by Pieter Brooshooft, as well as leestrommel, a set of magazines circulated by bookshops to subscribers. She also read cultural and scientific magazines as well as the Dutch women's magazine De Hollandsche Lelie, to which she began to send contributions which were published. From her letters, it was clear that Kartini read everything with a great deal of attention and thoughtfulness. The books she had read before she was 20 included &lt;a href="http://en.wikipedia.org/wiki/Max_Havelaar" title="Max Havelaar"&gt;Max Havelaar&lt;/a&gt; and Love Letters by &lt;a href="http://en.wikipedia.org/wiki/Multatuli" title="Multatuli"&gt;Multatuli&lt;/a&gt;. She also read De Stille Kracht (The Hidden Force) by &lt;a href="http://en.wikipedia.org/wiki/Louis_Couperus" title="Louis Couperus"&gt;Louis Couperus&lt;/a&gt;, the works of &lt;a href="http://en.wikipedia.org/wiki/Frederik_van_Eeden" title="Frederik van Eeden"&gt;Frederik van Eeden&lt;/a&gt;, &lt;a class="new" href="http://en.wikipedia.org/w/index.php?title=Augusta_de_Witt&amp;amp;action=edit&amp;amp;redlink=1" title="Augusta de Witt (page does not exist)"&gt;Augusta de Witt&lt;/a&gt;, the Romantic-Feminist author Mrs &lt;a class="new" href="http://en.wikipedia.org/w/index.php?title=Goekoop_de-Jong_Van_Beek&amp;amp;action=edit&amp;amp;redlink=1" title="Goekoop de-Jong Van Beek (page does not exist)"&gt;Goekoop de-Jong Van Beek&lt;/a&gt; and an anti-war novel by &lt;a class="mw-redirect" href="http://en.wikipedia.org/wiki/Berta_von_Suttner" title="Berta von Suttner"&gt;Berta von Suttner&lt;/a&gt;, Die Waffen Nieder! (Lay Down Your Arms!). All were in Dutch.&lt;/div&gt;&lt;div align="justify"&gt;Kartini's concerns were not just in the area of the emancipation of women, but also the problems of her society. Kartini saw that the struggle for women to obtain their freedom, autonomy and legal equality was just part of a wider movement.&lt;/div&gt;&lt;div align="justify"&gt;Kartini's parents arranged her marriage to Raden Adipati Joyodiningrat, the Regency Chief of &lt;a href="http://en.wikipedia.org/wiki/Central_Java" title="Central Java"&gt;Rembang&lt;/a&gt;, who already had three wives. She was married on the &lt;a href="http://en.wikipedia.org/wiki/November_12" title="November 12"&gt;12 November&lt;/a&gt; &lt;a href="http://en.wikipedia.org/wiki/1903" title="1903"&gt;1903&lt;/a&gt;. This was against Kartini's wishes, but she acquiesced to appease her ailing father. Her husband understood Kartini's aims and allowed her to establish a school for women in the east porch of the Rembang Regency Office complex. Kartini's only son was born on &lt;a href="http://en.wikipedia.org/wiki/September_13" title="September 13"&gt;September 13&lt;/a&gt;, &lt;a href="http://en.wikipedia.org/wiki/1904" title="1904"&gt;1904&lt;/a&gt;. A few days later on &lt;a href="http://en.wikipedia.org/wiki/September_17" title="September 17"&gt;September 17&lt;/a&gt;, &lt;a href="http://en.wikipedia.org/wiki/1904" title="1904"&gt;1904&lt;/a&gt;, Kartini died at the age of 25. She was buried in Bulu Village, Rembang.&lt;/div&gt;&lt;div align="justify"&gt;Inspired by Kartini's example, the Van Deventer family established the Kartini Foundation which built schools for women, 'Kartini's Schools' in &lt;a href="http://en.wikipedia.org/wiki/Semarang" title="Semarang"&gt;Semarang&lt;/a&gt; in 1912, followed by other women's schools in &lt;a href="http://en.wikipedia.org/wiki/Surabaya" title="Surabaya"&gt;Surabaya&lt;/a&gt;, &lt;a href="http://en.wikipedia.org/wiki/Yogyakarta" title="Yogyakarta"&gt;Yogyakarta&lt;/a&gt;, &lt;a href="http://en.wikipedia.org/wiki/Malang" title="Malang"&gt;Malang&lt;/a&gt;, &lt;a href="http://en.wikipedia.org/wiki/Madiun" title="Madiun"&gt;Madiun&lt;/a&gt;, &lt;a href="http://en.wikipedia.org/wiki/Cirebon" title="Cirebon"&gt;Cirebon&lt;/a&gt; and other areas.&lt;/div&gt;&lt;div align="justify"&gt;In 1964, President &lt;a href="http://en.wikipedia.org/wiki/Sukarno" title="Sukarno"&gt;Sukarno&lt;/a&gt; declared Kartini's birth date, &lt;a href="http://en.wikipedia.org/wiki/April_21" title="April 21"&gt;21 April&lt;/a&gt;, as 'Kartini Day' - an Indonesian National Holiday. This decision has been criticised. It has been proposed that Kartini's Day should be celebrated in conjunction with Indonesian Mothers Day, on &lt;a href="http://en.wikipedia.org/wiki/December_22" title="December 22"&gt;22 December&lt;/a&gt; so that the choice of Kartini as a national heroine would not overshadow other women who, unlike Kartini, took up arms to oppose the colonisers.&lt;/div&gt;&lt;div align="justify"&gt;In contrast, those who recognise the significance of Kartini argue that not only was she a feminist who elevated the status of women in Indonesia, she was also a &lt;a href="http://en.wikipedia.org/wiki/Nationalism" title="Nationalism"&gt;nationalist&lt;/a&gt; figure, with new ideas who struggled on behalf of her people, including her in the &lt;a href="http://en.wikipedia.org/wiki/Indonesian_National_Revolution" title="Indonesian National Revolution"&gt;national struggle for independence&lt;/a&gt;.&lt;/div&gt;&lt;div align="justify"&gt;&lt;b&gt;&lt;span style="color: #000099;"&gt;&lt;u&gt;Letters&lt;/u&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;&lt;div align="justify"&gt;After Kartini died, Mr JH Abendanon, the Minister for Culture, Religion and Industry in the East Indies, collected and published the letters that Kartini had sent to her friends in Europe. The book was titled Door Duisternis tot Licht (Out of Dark Comes Light) and was published in &lt;a href="http://en.wikipedia.org/wiki/1911" title="1911"&gt;1911&lt;/a&gt;. It went through five editions, with some additional letters included in the final edition, and was translated into &lt;a href="http://en.wikipedia.org/wiki/English_language" title="English language"&gt;English&lt;/a&gt; by Agnes L. Symmers and published under the title Letters of a Javanese Princess.&lt;/div&gt;&lt;div align="justify"&gt;The publication of Kartini's letters, written by a native Javanese woman, attracted great interest in the &lt;a href="http://en.wikipedia.org/wiki/Netherlands" title="Netherlands"&gt;Netherlands&lt;/a&gt; and Kartini's ideas began to change the way the Dutch viewed native women in Java. Her ideas also provided inspiration for prominent figures in the fight for Independence.&lt;br /&gt;There are some grounds for doubting the veracity of Kartini's letters. There are allegations that Abendanon made up Kartini's letters. These suspicions arose because Kartini's book was published at a time when the Dutch Colonial Government were implementing 'Ethical Policies' in the Dutch East Indies, and Abendanon was one of the most prominent supporters of this policy. The current whereabouts of the vast majority of Kartini's letters is unknown. According to the late Sulastin Sutrisno, the Dutch Government has been unable to track down JH Abendanon's descendants.&lt;/div&gt;&lt;div align="justify"&gt;&lt;b&gt;&lt;span style="color: #000099;"&gt;&lt;u&gt;Ideas&lt;/u&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;&lt;div align="justify"&gt;Condition of Indonesian women&lt;/div&gt;&lt;div align="justify"&gt;In her letters, Kartini wrote about her views of the social conditions prevailing at that time, particularly the condition of native Indonesian women. The majority of her letters protest the tendency of Javanese Culture to impose obstacles for the development of women. She wanted women to have the freedom to learn and study. Kartini wrote of her ideas and ambitions, including Zelf-ontwikkeling, Zelf-onderricht, Zelf-vertrouwen, Zelf-werkzaamheid and Solidariteit. These ideas were all based on Religieusiteit, Wijsheid en Schoonheid, that is, belief in God, wisdom, and beauty, along with Humanitarianisme (&lt;a href="http://en.wikipedia.org/wiki/Humanitarianism" title="Humanitarianism"&gt;humanitarianism&lt;/a&gt;) and Nationalisme (nationalism).&lt;/div&gt;&lt;div align="justify"&gt;Kartini's letters also expressed her hopes for support from overseas. In her correspondence with Estell "Stella" Zeehandelaar, Kartini expressed her desire to be like a European youth. She depicted the sufferings of Javanese women fettered by tradition, unable to study, secluded, and who must be prepared to participate in polygamous marriages with men they don't know.&lt;/div&gt;&lt;div align="justify"&gt;&lt;b&gt;Religion&lt;/b&gt;&lt;/div&gt;&lt;div align="justify"&gt;Kartini also expressed criticisms about &lt;a href="http://en.wikipedia.org/wiki/Religion" title="Religion"&gt;religion&lt;/a&gt;. She questioned why the &lt;a class="mw-redirect" href="http://en.wikipedia.org/wiki/Quran" title="Quran"&gt;Quran&lt;/a&gt; must be memorised and recited without an obligation to actually understand it. She also expressed the view that the world would be more peaceful if there was no religion to provide reasons for disagreements, discord and offence. She wrote "Religion must guard us against committing sins, but more often, sins are committed in the name of religion"&lt;/div&gt;&lt;div align="justify"&gt;Kartini also raised questions with the way in which religion provided a justification for men to pursue &lt;a href="http://en.wikipedia.org/wiki/Polygamy" title="Polygamy"&gt;polygamy&lt;/a&gt;. For Kartini, the suffering of Javanese women reached a pinnacle when the world was reduced to the walls of their houses and they were prepared for a polygamous marriage.&lt;/div&gt;&lt;div align="justify"&gt;&lt;b&gt;Further studies and teaching&lt;/b&gt;&lt;/div&gt;&lt;div align="justify"&gt;Kartini loved her father deeply although it is clear that her deep affection for him became yet another obstacle to the realisation of her ambitions. He was sufficiently progressive to allow his daughters schooling until the age of 12 but at that point the door to further schooling was firmly closed. In his letters, her father also expressed his affection for Kartini. Eventually, he gave permission for Kartini to study to become a teacher in Batavia (now &lt;a href="http://en.wikipedia.org/wiki/Jakarta" title="Jakarta"&gt;Jakarta&lt;/a&gt;), although previously he had prevented her from continuing her studies in the Netherlands or entering medical school in Batavia.&lt;/div&gt;&lt;div align="justify"&gt;Kartini's desire to continue her studies in Europe was also expressed in her letters. Several of her pen friends worked on her behalf to support Kartini in this endeavour. And when finally Kartini's ambition was thwarted, many of her friends expressed their disappointment. In the end her plans to study in the Netherlands were transmuted into plans to journey to Batavia on the advice of Mrs Abendanon that this would be best for Kartini and her younger sister, Rukmini.&lt;/div&gt;&lt;div align="justify"&gt;Nevertheless, in 1903 at the age of 24, her plans to study to become a teacher in Batavia came to nothing. In a letter to Mrs Abendanon, Kartini wrote that the plan had been abandoned because she was going to be married... "In short, I no longer desire to take advantage of this opportunity, because I am to be married..". This was despite the fact that for its part, the Dutch Education Department had finally given permission for Kartini and Rukmini to study in Batavia.&lt;/div&gt;&lt;div align="justify"&gt;As the wedding approached, Kartini's attitude towards Javanese traditional customs began to change. She became more tolerant. She began to feel that her marriage would bring good fortune for her ambition to develop a school for native women. In her letters, Kartini mentioned that not only did her esteemed husband support her desire to develop the woodcarving industry in Jepara and the school for native women, but she also mentioned that she was going to write a book. Sadly, this ambition was unrealised as a result of her premature death in 1904 at the age of 25.&lt;/div&gt;&lt;div align="justify"&gt;Source : &lt;a href="http://en.wikipedia.org/wiki/Kartini"&gt;http://en.wikipedia.org/wiki/Kartini&lt;/a&gt; &lt;/div&gt;&lt;script src="http://kumpulblogger.com/sca.php?b=128" type="text/javascript"&gt;&lt;/script&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-471117174093502805?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/471117174093502805/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=471117174093502805&amp;isPopup=true' title='0 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/471117174093502805'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/471117174093502805'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2008/04/raden-ayu-kartini.html' title='Raden Ayu Kartini'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://3.bp.blogspot.com/_SdqJVc93gs8/SA9wZ_TmeOI/AAAAAAAAACo/d_jeTMVDpUY/s72-c/Raden_Adjeng_Kartini.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-8197281299330729225</id><published>2008-04-16T11:15:00.000-07:00</published><updated>2008-04-16T11:28:45.981-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='humor'/><title type='text'>Pelajaran Matematika SD</title><content type='html'>Aku dapat sedikit humor matematika.

He wrote the Kitâb al-Jem wa'l Tafrîq bi Hisâb al-Hind also called Kitâb Hisâb al-adad al-Hindî on arithmetic in which he used Indian numerals including zero in place of depicting numbers by the letters of the alphabet and the decimal notations or numeration by position" for the first time. It deals with the four basic operations of addition, subtraction, multiplication and division as well as with both common and sexagesimal fractions and the extraction of the square root. The original Arabic text of the book is lost and its only Latin translation is available.&lt;/p&gt;&lt;p align="justify"&gt;Other mathematical writings of Mûsâ Al-Khwârazmî are also not known. His best known classical work on algebra is the Kitâb al-Mukhtasar fî Hisâb al-Jabr wa'l Muqâbala. It was also translated into Latin in the Middle Ages and holds an eminent place in the history of mathematics, firstly, in the words of Galal S.A. Shawki, because it defined algebra as an independent disciple in mathematics, and secondly because it accelerated the introduction of the Arabic place value numbering into the West. The book is devoted to finding solutions to practical problems which Muslims encountered in daily life concerning matters of inheritance, legacies, partition, lawsuits and commerce, with over eight hundred examples. The original work in Arabic was written in 820 A.D. and was translated into Latin in the twelfth century. It is worth remarking that the term al-jabr, in the Latinized form of algebra, has found its way into the language of Europe, whiles the old mathematical term, algorism, is a distortion of al-Khwârazmî's name.&lt;/p&gt;&lt;p align="justify"&gt;The meaning of the Arabic word Al-Jabr is restoration by transposing negative quantities to the other side of the equation to make them positive and the term Al-Muqâbalah refers to the process of eliminating identical quantities from the two sides of the equation. But the best translation for Hisâb al-Jabr wa'l-Muqâbala, according to John K. Baumgart, is 'the science of equations'. The algebra of Mûsâ al-Khwârazmî was rhetorical in form. Al-Khwârazmî had given the rules for the solution of quadratic equations which are supported in a number of cases by geometrical proofs also. The unknown quantity, in the words of Galal S.A. Shawki, was termed the "thing" (shay) or "root" (jazr); the latter means in Arabic the origin or base, also the root of a tree, hence, the use of the expression "root of an equation" is derived from the Arabic concept. Mûsâ al-Khwârazmî had used the Arabic word for root to denote the first degree term of a quadratic equation. Explaining in detail he says, "The following' is an example of squares equal to roots, a square is equal to 5 roots. The root of the square then is 5, and 25 forms its square, which of course equals 5 of its roots." For the second power of a quantity he employs mâl (wealth, property) which is also used to mean only "quantity" and dirham is used as unit of coinage.&lt;/p&gt;&lt;a href="http://www.muslimheritage.com/uploads/figure%2023.jpg"&gt;&lt;img style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 200px; CURSOR: hand" alt="" src="http://www.muslimheritage.com/uploads/figure%2023.jpg" border="0" /&gt;&lt;/a&gt;&lt;br /&gt;&lt;div align="justify"&gt;The bases of algebra, first viewed as an independent mathematical discipline , were laid down by Mûsâ al-Khwârazmî who carefully formulated analytical solutions of the various forms of quadratic equation and profusely illustrated his method of solution by practical examples. He was quite aware of the existence of two roots of the quadratic equation, though he cared for positive, real roots only.&lt;br /&gt;His Hisâb al-Jabr wa'l-Muqâbalah is actually on applied mathematics. Its first part discusses the equations of the first and second degrees. All his proposed problems can be reduced to one of the six standard forms. He gives rules for the solution of each of the six forms and explains how to reduce any given problem to one of these standard forms with examples. The second part of the book deals with practical mensuration by giving rules for finding the area of various plane figures including the circles, and for finding the volume of a number of solids including cones and pyramids. The third part concerns legacies as well as inheritance and is the longest. It consists entirely of solved problems which arise out of legacies.&lt;/div&gt;&lt;p&gt;Contribution to Geography&lt;/p&gt;&lt;p&gt;Mûsâ al-Khwârazmî had also contributed to the science of geography. As the book of Geography of Claudius Ptolemy (2nd century A.D.) was translated several times into Arabic he had a model for writing his book in this field of knowledge. His book on geography entitled Kitâb Sûrat al-Ard (Book of the image of the earth) consists almost entirely of lists of longitudes as well as latitudes of localities and gives in a tabulated form the coordinates of the places like cities, mountains, seas, rivers, islands etc. The book is arranged according to the Greek system of the seven climes (aqâlim) giving contemporary data but the knowledge acquired by the other Muslims are also incorporated into it. The first section lists cities, the second, mountains (giving the coordinates of their extreme points and their orientation); the third, seas (giving the coordinates of salient point on their coastlines and a rough description of their outlines); the fourth, islands (giving the coordinates of their centres, and their length and breadth); the fifth, the central points of various geographical regions; the sixth, rivers (giving their salient points and towns on them). This book had served as a basis for later works and stimulated geographical studies and the composition of original treatises. It is said that his Kitâb Sûrat al-Ard was also accompanied by regional maps of each of the climes and by a single world map called "al-Sûrat al-Ma'muniyya" but have been lost. It is also said that his map of the world was the first map of the heavens and the world drawn by Muslims. But the editor of the Kitâb Sûrat al-Ard Hans von Mzik, has produced only four maps. These four maps, in the words of S. Maqbul Ahmad, seem to be later recessions of the original maps. But Ibrahim Shawkat reasons that since Al-Khwârazmî wrote a brief work on geography, he did not draw a complete map of the world but confined himself to draw only the four maps as an illustration. His source of inspiration might possibly have been the mappa mundi constructed for Caliph Al-Ma'mun by a team of geographers in which Al-Khwârazmî himself would have been included.&lt;/p&gt;&lt;p&gt;Figure SourcesFigure (front).

Geert Wilders sepertinya lupa bahwa masyarakat Islam adalah masyarakat yang tidak akan mentolerir segala macam penghinaan yang ditujukan terhadap Agamanya (Islam). Dari sinopsis film Fitna yang saya baca di Wikipedia.com, saya bisa menarik kesimpulan bahwa Geert Wilders dan masyarakat takut dengan perkembangan Islam di Netherlands. Sebagai bukti, diakhir film Fitna dipampang tulisan "Stop Islamisation in Netherlands".&lt;/div&gt;&lt;p align="justify"&gt;Kalo boleh saya bilang, Geert Wilders bermaksud ingin mengkampanyekan penghentian perkembangan Islam di Belanda, tapi bukannya berhasil meredam perkembangan Islam malah membangunkan "Macan" yang sedang tidur. Kaciaaaan dech si Geert Wilders. &lt;/p&gt;&lt;p align="justify"&gt;Himbauan buat sesama Muslim dimanapun berada. Mari kita sikapi peredaran film fitna secara jantan. Dalam arti tidak dengan menggunakan kekerasan dan anarkhisme. Mari kita sikapi peredaran film fitna ini sebagai bukti ketakutan Dunia Barat dengan perkembangan Islam yang begitu pesat. Mereka takut Islam akan berjaya lagi seperti pada zaman keemasannya dulu.&lt;/p&gt;&lt;p align="justify"&gt;Oke.... tetap ikuti perkembangan dan manuver politik yang dilakukan oleh Orang-orang yang tidak suka dengan Islam. Jangan lupa, mereka begitu gigih mempelajari Al-Qur`an dan Al-Hadits untuk menghancurkan kita. Maka kitapun jangan kalah. Pelejari apa yang mereka punya untuk kita jadikan sebagai landasan dalam berargumentasi melawan mereka. Sehingga mereka akan terkalahkan bukan hanya oleh Al-Qur`an dan Al-Hadits yang sudah jelas-jelas benar. Tapi kita dapat mengalahkan mereka dengan sumber-sumber mereka (Injil dan lainnya).&lt;/p&gt;&lt;p align="justify"&gt;Shohabat Ali r.a pernah berkata :&lt;/p&gt;&lt;p align="justify"&gt;"Kejahatan / Kebathilan yang TERORGANISIR dengan BAIK akan dapat MENGALAHKAN KEBAIKAN yang TIDAK TERORGANISIR".&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-1295213641703384160?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/1295213641703384160/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=1295213641703384160&amp;isPopup=true' title='0 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/1295213641703384160'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/1295213641703384160'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2008/04/film-fitna.html' title='Film Fitna....'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-751899101763217679</id><published>2008-04-05T12:13:00.000-07:00</published><updated>2008-04-05T12:26:36.796-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Article'/><title type='text'>Software for Graphics and Data Analysis</title><content type='html'>&lt;a href="http://stommel.tamu.edu/~baum/ocean_graphics.html#copyright"&gt;Copyright&lt;/a&gt; 1995-2004 by S. Baum&lt;br /&gt;&lt;p align="justify"&gt;As the data we collect from high-bandwidth instruments (e.g. sensors on satellites) and the output we obtain from high resolution numerical simulations threaten to overwhelm us with gigabytes of numbers devoid of meaning, we must develop and use data analysis and graphing tools as complicated as, if not more so, those used to produce the numbers. Fortunately, for the folks who need to use such tools and don't have a year or so to spare designing and building one, there are quite a few of these tools freely available on the Web. Some are the finished products of research groups (or, in some cases, individuals), and some are continually being developed and welcome user input for improvements or additions.&lt;/p&gt;&lt;p align="justify"&gt; I've collected these tools and list them below in in three broad categories which (inevitably) overlap to some extent. The &lt;a href="http://stommel.tamu.edu/~baum/graphics-graph.html"&gt;first group&lt;/a&gt; contains links to software that is chiefly designed for graphing 2-D (and less often but moreso all the time 3-D) data. These range from the simplest (in concept and design) packages for quickly drawing 2-D graphs to systems for creating 3-D graphs with animation, ray-tracing, texture-mapping, and various other capabilities. As you might expect, the more complicated the package gets the more onerous are the hardware requirements. Most of the packages also contain simple data handling capabilities such as multiplying the data being plotted by a constant, although that is not their main purpose.&lt;/p&gt;&lt;p align="justify"&gt; The &lt;a href="http://stommel.tamu.edu/~baum/graphics-analysis.html"&gt;second group&lt;/a&gt; features software that is largely concerned with number crunching tasks, especially the manipulation of large and multi-dimensional matrices. These usually feature some sort of native interpreted language that allows a complicated series of mathematical operations such as matrix inversion, multiplication, and the like to be performed on one's data using a job script. Some also feature graphics capabilities but, at least as far as I can tell, that is not their primary function.&lt;/p&gt;&lt;p align="justify"&gt; The &lt;a href="http://stommel.tamu.edu/~baum/graphics-formats.html"&gt;third group&lt;/a&gt; consists of software for storing various types of data in a standard and/or compressed format so we don't spend too much of our lives converting data from one obscure format to another. These are usually libraries of functions that are called from the programs we use to create or read the original data. Initially these can be a bit of a pain to use, but in the long-term the consistency and parsimony of storage as well as the portability of our data sets make these well worth the effort.&lt;/p&gt;&lt;p align="justify"&gt; I'll stick mainly to describing the packages in their own words, reserving any editorial comments for the software I've actually had the pleasure to use enough to form an opinion. I'll also mention analogous commercial packages where it seems appropriate and supply an additional listing of those I deem needing more than a passing mention. This is going to be overwhelmingly (i.e. totally, completely, utterly, etc.) biased towards packages that will run in UNIX workstation environments, with a not-so-subtle additional bias (at least in the way of reviews) towards those that will run on &lt;a href="http://stommel.tamu.edu/~baum/linuxlist.html"&gt;Linux&lt;/a&gt; platforms.&lt;/p&gt;&lt;p align="justify"&gt; Please send me email if you have any suggestions for corrections or additions to this list. There's always room for one more here. I'd also appreciate immediate notification of any dead links. Also, do not ask me to assist in installing any of the following software. Any request for this type of help will most likely be ignored. There's just no way I can serve as a consultant, free or otherwise, for over a hundred different software packages. The packages or package sites usually contain information on how to contact the author(s). Contact them. They wrote the software; I just use some of it. Consider this site beerware: if you ever meet me, then you owe me one.&lt;/p&gt;&lt;p align="justify"&gt; You can search for packages via the categories listed below.&lt;/p&gt;&lt;ul&gt;&lt;li&gt;&lt;a href="http://stommel.tamu.edu/~baum/graphics-graph.html"&gt;Mostly graphics (105)&lt;/a&gt; &lt;/li&gt;&lt;li&gt;&lt;a href="http://stommel.tamu.edu/~baum/graphics-analysis.html"&gt;Mostly numerical analysis and number crunching (22)&lt;/a&gt; &lt;/li&gt;&lt;li&gt;&lt;a href="http://stommel.tamu.edu/~baum/graphics-formats.html"&gt;Mostly data formats (9)&lt;/a&gt; &lt;/li&gt;&lt;/ul&gt;&lt;p&gt;Note: I have no plans to update any of the following sections. Consider them as nothing more than historical snapshots of rapidly evolving fields.&lt;/p&gt;&lt;p&gt; I've added some new sections that fit in sort of sideways with the above. There's a new section that describes various symbolic algebra/mathematics/etc. packages and another that details various freely available GUI builders, i.e. packages that let you develop graphical user interfaces to your programs/packages/systems. The symbolic math section doesn't really fit in with the number crunching etc. software, nor the does GUI section fit in with the graphics section, but they're not unrelated and as such have been given separate sections. Other new sections (well, new to this page) are a page I've developed concerning software and information pertaining to wavelets, which are turning out to be quite useful in many data analysis applications, and a page on general spectral analysis software and documents.&lt;/p&gt;&lt;ul&gt;&lt;li&gt;&lt;a href="http://stommel.tamu.edu/~baum/graphics-math.html"&gt;Mostly symbolic mathematics (10)&lt;/a&gt; &lt;/li&gt;&lt;li&gt;&lt;a href="http://stommel.tamu.edu/~baum/graphics-GUI.html"&gt;Mostly GUI development systems (31)&lt;/a&gt; &lt;/li&gt;&lt;li&gt;&lt;a href="http://stommel.tamu.edu/~baum/wavelets.html"&gt;Wavelet software and information&lt;/a&gt;&lt;br /&gt;&lt;a href="http://stommel.tamu.edu/~baum/spectrum.html"&gt;Spectral analysis&lt;/a&gt; &lt;/li&gt;&lt;/ul&gt;&lt;p&gt;This document is freely reproducible for educational, i.e. nonprofit, purposes in which context copies can be made provided that, at the very least, the author is credited and a link to the home site is maintained.

Untuk membebaskan dan memulangkan mereka ke Indonesia, keluarga diminta menebus 3.500 dolar AS/orang atau sekitar Rp 34 juta/orang.&lt;/div&gt;&lt;p align="justify"&gt;Kepala Departemen Informasi dan Dokumentasi Serikat Buruh Migran Indonesia (SBMI) Jamaludin mengatakan, TKI asal Brebes itu telah disandera Agensi Buska Irak selama lima bulan. &lt;/p&gt;&lt;p align="justify"&gt;Alasannya, mereka dituding sebagai mata-mata Amerika Serikat. Agensi meminta tebusan 3.500 dolar AS/orang kepada keluarga, bila mereka ingin dibebaskan. &lt;/p&gt;&lt;p align="justify"&gt;Dari 16 TKI itu, kata dia, tiga orang telah diketahui identitasnya. Yakni, Supriyatin (26), warga Desa Prapag Kidul, Kecamatan Losari; Hidayah (35), warga Desa  Luwungbata, Kecamatan Tanjung; dan Murni (32) warga Desa Krakahan, Kecamatan Tanjung. &lt;/p&gt;&lt;p align="justify"&gt;"Kasus ini sudah kami laporkan ke Departemen Luar Negeri (Deplu) dan BP2TKI. Deplu kini tengah berkoordinasi dengan International Organization for Migrant (IOM) karena tidak ada perwakilan Indonesia di Irak. Ini menjadi kendala upaya pemulangan mereka," ungkapnya, Senin (31/3).&lt;/p&gt;&lt;p align="justify"&gt;&lt;strong&gt;Habis Kontrak&lt;/strong&gt;&lt;/p&gt;&lt;p align="justify"&gt;Ia mengatakan, terungkapnya kasus tersebut berawal dari laporan keluarga TKI karena hingga kini tidak ada kejelasan nasib dan hilang kontak. Padahal, sesuai perjanjian kerja mereka semestinya sudah pulang, karena masa kontraknya habis.&lt;/p&gt;&lt;p align="justify"&gt;”Dari hasil pelacakan lembaga kami di Kedutaan Besar (Kedubes) RI, di Yordania, diketahui mereka disandera agensi. Irak sebenarnya merupakan negara larangan mengirim TKI, karena sebagai daerah konflik,” jelasnya.Data tersebut, lanjut dia, diperkuat keterangan Supriyatin, salah satu korban, yang berhasil dihubungi melalui telepon. Diperoleh informasi jumlah TKI yang disandera sebanyak 16 orang dan seluruhnya asal Brebes. ”Kami terus berupaya agar para TKI bisa segera dipulangkan,” tandasnya.&lt;/p&gt;&lt;p align="justify"&gt;Kiki Tobi’in (30), kakak Supriyatin, meminta pemerintah serius menangani kasus itu dan berharap bisa segera dipulangkan. Sebab, mereka di tempat penyanderaan sangat menderita. ”Kami pasrah dan hanya berharap kepada pemerintah, karena untuk membayar tebusan kami tidak mampu,” tuturnya.&lt;/p&gt;&lt;p align="justify"&gt;Kasi Penempatan Tenaga Kerja Dinas Kependudukan, Catatan Sipil, Tenaga Kerja dan Transmigrasi Pemkab Brebes, Ronald Jasper mengatakan, hingga kini pihaknya belum menerima laporan kasus itu. Instansinya belum bisa menindaklanjuti karena proses penyelesaian membutuhkan data. ”Kalau laporan masuk, kami siap dan segera menindaklanjuti,” ujarnya.&lt;/p&gt;&lt;p align="justify"&gt;Petugas Bagian Perlindungan WNI Deplu, Suseno, ketika dihubungi wartawan lewat telepon mengatakan, telah menerima laporan terkait kasus tersebut. Namun, masih dalam pelacakan untuk mengetahui para TKI itu. Apakah semuanya dari Brebes atau tidak perlu informasi lebih detail. SBMI juga diminta membuat laporan resmi ke Direktur Perlindungan WNI dan BHI Deplu. ”Kami masih berkoordinasi dengan lembaga internasional untuk mengusut kasus ini. Sebab, Indonesia tidak mempunyai perwakilan di Irak,” terangnya.

For some of us – perhaps its more accurate to say only a few – these strange functions were met with fascination and glee, representing the first real encounter with non-trivial mathematics. In most cases, the presentation of trigonometry is delivered in the context of problems involving triangles, which quite rapidly become rather repetitive and dull. Consequently, many students do not appreciate the crucial relevance and importance of trigonometry in solving more interesting and complex problems, drawn from astronomy, cartography and navigation, to name a few fields. Moreover, merrily determining unknown angles and sides of triangles with full dependence on the calculator, we do not stop to ask how, say, the sine of a particular angle could be worked out without a computing machine, relying on pen, paper and human ingenuity alone. The birth of trigonometry lies in astronomy, one of the most vigorously studied sciences by the Muslims, particularly due to its relevance in determining the exact times of the ritual prayers. But even before the Muslims, Greek astronomers were calculating the unknown sides and angles of certain triangles, given the value of the remaining sides or angles, in order to understand the motion of the sun, moon and the, then known, five planets.&lt;/div&gt;&lt;br /&gt;&lt;br /&gt;&lt;p align="justify"&gt;&lt;span style="font-size:85%;"&gt;&lt;a href="http://www.muslimheritage.com/uploads/Ottoman_Almanac.jpg"&gt;Figure 1&lt;/a&gt;.

The most thorough treatment of the subject is to be found in The Almagest of Ptolemy, an astronomer working in Alexandria in the early part of the second century A.D. Ptolemy's treatise reached European scholars through Muslim hands, who rendered the original Greek title (which meant The Great Arrangement) in more succinct and superlative terms through a combination of transliteration and pre-pending to produce Al-Majest, simply meaning The Greatest, thus reflecting the esteemed position the work enjoyed in Muslim scholarly circles. Hellenist astronomers would draw principally upon a table found in Book I of Almagest which was denoted "A Table of Chords in a Circle," to solve all their plane trigonometric problems. For arcs at angles in increments of half a degree up to 180 degrees, the table gives the lengths of the chords subtending the angles in a circle of radius 60 units. In his work, The Transversal Figure, the thirteenth century Muslim astronomer Nasir al-Din Al-Tûsî explains how this table of chord lengths is employed to solve problems relating to right angled triangles. Al-Tûsî makes the crucial observation that establishes the link between triangles and arcs of circles: any triangle may be inscribed in a circle, and therefore, its sides may be viewed as the chords subtending the arcs opposite the angles of the triangle. The drawback of such reliance on these tables was twofold. Firstly, considerable manipulation of the table and intermediate steps were required to solve all the variations that might arise in solving unknown lengths or angles of a right triangle. This is in contrast to using the six familiar trigonometric functions – the sine, cosine and tangent and their reciprocals, the secant, cosecant and cotangent – that are characteristic of modern techniques, which were first devised and arranged in a systematic way by Muslim mathematicians. The second inconvenience of the chord length tables is that they often required angles to be doubled in order to calculate the length of an arc.&lt;/p&gt;&lt;span style="font-size:85%;"&gt;&lt;a href="http://www.muslimheritage.com/uploads/Sawr_Jawza.jpg"&gt;Figure 2.&lt;/a&gt; Miniature illustrations of Sawr (Taurus) and Jawzâ (Gemini).

Istanbul University Library, T 5393.&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;p align="justify"&gt;Actually, a chain of Muslim scholars before the 10th century had already laid the foundations of trigonometry, paving the way for Nasir al-Din Al-Tûsî to collect, organise and elaborate the contributions. It was Mohammed Ibn Jabir ibn Sinan Abu Abdullah, known as Al-Battani, for he was born in Battan, Mesopotamia, who is one of the most influential figures in trigonometry. He was an Arab Prince, the Governor of Syria, and is considered to be the greatest Muslim astronomer and mathematician, eventually dying in Damascus in 929 CE. His motivation for pioneering the study of trigonometry was his observations on the movements of planets:&lt;/p&gt;&lt;p align="justify"&gt;&lt;em&gt;&lt;span style="font-size:85%;"&gt;"… after having lengthily applied myself in the study of this science, I have noticed that the works on the movements of the planets differed consistently with each other, and that many authors made errors in the manner of undertaking their observation, and establishing their rules. I also noticed that with time, the position of the planets changed according to recent and older observations; changes caused by the obliquity of the ecliptic, affecting the calculation of the years and that of eclipses. Continuous focus on these things drove me to perfect and confirm such a science."&lt;/span&gt;&lt;/em&gt;&lt;/p&gt;&lt;p align="justify"&gt;More crucially, al-Battani, explained his mathematical operations and urged others "to continue observation, and to search," in order to perfect and expand his work. As well as Al-Battani, Abu al-Wafa, Ibn Yunus and Ibn al-Haytham all developed spherical trigonometry and applied it to the solution of astronomical problems.&lt;/p&gt;&lt;p align="justify"&gt;Al-Battani was the first to use the expressions "sine" and "cosine", defining them as lengths, rather than ratios as we know them today; the original definition of the sine is easily retrieved from the modern version by multiplying by the hypotenuse of the triangle in question. The tangent was referred to by Al-Battani as the "extended shadow," the shadow of a notional horizontal rod mounted on a wall. Al-Bîrûnî (973-1048 CE) defined the trigonometric functions of tangent and cotangent, which were inherited in a tentative form from the Indians. Al-Bîrûnî was among those who laid the foundation for modern trigonometry; Mohammed ibn Musa al-Khwarizmi, born in 780 CE, developed the sine, cosine and trigonometric tables, which were later, translated to the West. It would be another 500 years though before the trigonometry of tangents was discovered by modern mathematics and then another 100 years before Copernicus was aware of it.&lt;/p&gt;&lt;p align="justify"&gt;In closing, it is worth mentioning a few of the other important achievements in the area of trigonometry by Muslims, and also the remarkable application by Al-Bîrûnî in measuring the circumference of the Earth. The indispensable Sine Law was stated and proved by Nasir al-Din Al-Tûsî by drawing upon and cunningly employing elementary ideas of geometry. He then proceeded to apply the law to solve all kinds of problems in a systematic fashion. Abu al-Wafa' proved the familiar addition theorem for sines, which is a lot more efficient and elegant as compared to the original statement in Almagest involving chord lengths. Before the advent of computers, it was important to construct accurate tables of key functions for regular spaced values of the function argument. This was a painstaking and labour intensive procedure; in the case of trigonometric tables, it was required first to have a very precise way of calculating the sine of 1 degree, and second, a set of rules for interpolating based on the tables. Both these issues were the subject of critical investigation by a number of Muslim scholars, such as Al-Bîrûnî, Ibn Yunus and Al-Kashi. To reach an approximation of the sine of 1 degree, Al-Kashi uses a procedure which in modern parlance is referred to as an iterative method.&lt;/p&gt;&lt;p align="justify"&gt;The Greeks were fond of conducting geodic surveys for determining various fundamental distances related to the earth, such as its circumference. One such method is described by Ptolemy in his Geography. Al-Bîrûnî was known for his characteristic dry humour and uses it to full effect to introduce his method for calculating the circumference of the earth: "Here is another method for the determination of the circumference of the earth. It does not require walking in deserts." The experiment was conducted while he was travelling with King Mahmud of Ghazna in what we now know as northwest India. He recorded his expeditious account in On the Determination of the Coordinates of Cities. The method is undertaken from the summit of a mountain and requires knowledge of its height, and so, Al-Bîrûnî first sets out the method by which this quantity is determined. As Al-Bîrûnî records, he employed the method on a mountain near Nandana in India : &lt;em&gt;"When I happened to be living in the fort of Nandana in the land of India, I observed from an adjacent high mountain standing west of the fort a large plan lying south of the mountain. It occurred to me I should examine this method there."&lt;/em&gt;&lt;/p&gt;&lt;p align="justify"&gt;The final value for the circumference was found to match the value determined by the more elaborate procedure involving a geodetic survey. As Berggren states&lt;em&gt;,"It doubtless gladdened al-Bîrûnî's heart to show that a simple mathematical argument combined with a measurement could do as well as two teams of surveyors tramping about in the desert."&lt;/em&gt;&lt;/p&gt;&lt;p align="justify"&gt;Trigonometry can now be added to the list of essential areas of knowledge mastered by the Muslims and subsequently conveyed to Europe through various routes. The contribution is eloquently summarised by Berggren :&lt;/p&gt;&lt;p align="justify"&gt;&lt;em&gt;"We have seen in the preceding sections that Muslim mathematicians organized trigonometry into a systematic discipline, whose theory rested on a full complement of six functions and a variety of powerful results, such as the Law of Sines and certain key trigonometric identities … Thus trigonometry takes its place, alongside algebra and arithmetic, as part of our heritage from Islamic mathematics."&lt;/em&gt;&lt;/p&gt;&lt;p align="justify"&gt;* Dr Mahbub Ghani is a Lecturer at King's College, University of London.&lt;br /&gt;by: Dr. Mahbub Ghani, Fri 02 February, 2007&lt;/p&gt;&lt;p align="justify"&gt;Source : &lt;/p&gt;&lt;p align="justify"&gt;&lt;a href="http://muslimheritage.com/topics/default.cfm?TaxonomyTypeID=12&amp;amp;TaxonomySubTypeID=61&amp;amp;TaxonomyThirdLevelID=-1&amp;amp;ArticleID=662"&gt;http://muslimheritage.com/topics/default.cfm?TaxonomyTypeID=12&amp;amp;TaxonomySubTypeID=61&amp;amp;TaxonomyThirdLevelID=-1&amp;amp;ArticleID=662&lt;/a&gt;&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-220570831779958393?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/220570831779958393/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=220570831779958393&amp;isPopup=true' title='0 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/220570831779958393'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/220570831779958393'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2008/03/sine-cosine-and-measurement-of-earth.html' title='Sine, Cosine and the Measurement of the Earth'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-7203771718716967017</id><published>2008-03-23T11:43:00.000-07:00</published><updated>2008-03-23T12:00:47.314-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='artikel islam'/><category scheme='http://www.blogger.com/atom/ns#' term='Article'/><title type='text'>The Ancien Piri Reis Map</title><content type='html'>&lt;a href="http://www.uwgb.edu/dutchs/TECHFOTO/MEDIEVAL/pirireis.jpg"&gt;&lt;img style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 320px; CURSOR: hand" alt="" src="http://www.uwgb.edu/dutchs/TECHFOTO/MEDIEVAL/pirireis.jpg" border="0" /&gt;&lt;/a&gt; The Map&lt;br /&gt;&lt;p align="justify"&gt;The Piri Reis Map, shown on the left, is the oldest surviving map to show the Americas. It is not European, surprisingly, but Turkish. It bears a date of 919 in the Moslem calendar, corresponding to 1513 in the Western Calendar. It is in the Topkapi Palace in Istanbul, a fabulous museum and the locale for a truly awful movie in the late 1960's. (I've been there - the real place bears no resemblance to the place in the movie.) The map was lost for a long time and only rediscovered in the 20th century.&lt;/p&gt;&lt;p align="justify"&gt;Apart from its great historic interest, the map has been alleged to contain details no European could have known in the 1500's, and therefore proves the existence of ancient technological civilizations, visits by extraterrestrials, or both. &lt;/p&gt;&lt;p align="justify"&gt;The map is a portolan chart, a common form at this time. Instead of latitude and longitude grids, compass roses were placed at key points with azimuths radiating from them. That said, the east-west lines through the small rose off South America in the center of the map are a very good approximation to the Equator, both there and with respect to Africa. The small one at the very top of the map is a very good estimate of 45 north where the east-west azimuth hits the coast of France. The two big compass roses in mid-Atlantic are harder to place. They might locate the tropic lines (23-1/2 north and south) or they could represent 22-1/2 latitude (one-fourth of the way from equator to pole). Considering they are a bit closer to 45 degrees than the equator, the tropic lines are the best bet.&lt;/p&gt;&lt;p align="justify"&gt;&lt;em&gt;&lt;a href="http://www.uwgb.edu/dutchs/PSEUDOSC/PiriRies.HTM"&gt;read more.........&lt;/a&gt;&lt;/em&gt;&lt;/p&gt;&lt;p align="justify"&gt;Source from : &lt;a href="http://www.uwgb.edu/"&gt;http://www.uwgb.edu/&lt;/a&gt; &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-7203771718716967017?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/7203771718716967017/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=7203771718716967017&amp;isPopup=true' title='14 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/7203771718716967017'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/7203771718716967017'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2008/03/ancien-piri-reis-map.html' title='The Ancien Piri Reis Map'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>14</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-3856963143248543965</id><published>2008-03-23T11:31:00.000-07:00</published><updated>2008-03-23T11:42:59.154-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='artikel islam'/><title type='text'>Asal-usul kata Algoritma</title><content type='html'>&lt;p align="justify"&gt;Istilah algoritma, mungkin bukan sesuatu yang asing bagi kita. Teman-teman ada yang tahu arti kata ‘algoritma’? Ditinjau dari asal-usul katanya, kata ‘Algoritma’ mempunyai sejarah yang agak aneh. Orang hanya menemukan kata Algorism yang berarti proses menghitung dengan angka Arab. Seseorang dikatakan ‘Algorist’ jika menghitung menggunakan angka Arab. Para ahli bahasa berusaha menemukan asal kata ini namun hasilnya kurang memuaskan. Akhirnya para ahli sejarah matematika menemukan asal kata tersebut yang berasal dari nama penulis buku Arab terkenal, yaitu Abu Abdullah Muhammad Ibnu Musa Al-Khuwarizmi dibaca orang barat menjadi Algorism.&gt;&lt;/p&gt;&lt;p align="justify"&gt;Definisi Algoritma&lt;/p&gt;&lt;p align="justify"&gt;Definisi Algoritma adalah langkah-langkah logis penyelesaian masalah yang disusun secara sistematis dan logis. Contoh sederhana adalah penyusunan sebuah resep makanan, yang biasanya terdapat langkah-langkah cara memasak masakan tersebut. Tapi, algoritma umumnya digunakan untuk membuat diagram alur (flowchart) dalam ilmu komputer / informatika.&lt;/p&gt;&lt;p align="justify"&gt;Penemu konsep Algoritma dan Aljabar&lt;/p&gt;&lt;p align="justify"&gt;Penemunya adalah seorang ahli matematika dari uzbekistan yang bernama Abu Abdullah Muhammad Ibn Musa al-Khwarizmi. Di literatur barat, beliau lebih terkenal dengan sebutan Algorism. Panggilan inilah yang kemudian dipakai untuk menyebut konsep algoritma yang ditemukannya. Abu Abdullah Muhammad Ibn Musa al-Khwarizmi (770-840) lahir di Khwarizm (Kheva), kota di selatan sungai Oxus (sekarang Uzbekistan) tahun 770 masehi. Kedua orangtuanya kemudian pindah ke sebuah tempat di selatan kota Baghdad (Irak), ketika ia masih kecil. Khwarizm dikenal sebagai orang yang memperkenalkan konsep algoritma dalam matematika, konsep yang diambil dari nama belakangnya.&lt;/p&gt;&lt;p align="justify"&gt;Al khwarizmi juga adalah penemu dari beberapa cabang ilmu matematika yang dikenal sebagai astronom dan geografer. Ia adalah salah satu ilmuwan matematika terbesar yang pernah hidup, dan tulisan-tulisannya sangat berpengaruh pada jamannya. Teori aljabar juga adalah penemuan dan buah pikiran Al khwarizmi. Nama aljabar diambil dari bukunya yang terkenal dengan judul Al Jabr Wa Al Muqabilah. Ia mengembangkan tabel rincian trigonometri yang memuat fungsi sinus, kosinus dan kotangen serta konsep diferensiasi.&lt;/p&gt;&lt;p align="justify"&gt;Pengaruhnya dalam perkembangan matematika, astronomi dan geografi tidak diragukan lagi dalam catatan sejarah. Pendekatan yang dipakainya menggunakan pendekatan sistematis dan logis. Dia memadukan pengetahuan dari Yunani dengan Hindu ditambah idenya sendiri dalam mengembangkan matematika. Khwarizm mengadopsi penggunaan angka nol, dalam ilmu aritmetik dan sistem desimal. Beberapa bukunya banyak diterjemahkan kedalam bahasa latin pada awal abad ke-12, oleh dua orang penerjemah terkemuka yaitu Adelard Bath dan Gerard Cremona. Risalah-risalah aritmetikanya, seperti Kitab al-Jam’a wal-Tafreeq bil Hisab al-Hindi, Algebra, Al-Maqala fi Hisab-al Jabr wa-al-Muqabilah, hanya dikenal dari translasi berbahasa latin. Buku-buku itu terus dipakai hingga abad ke-16 sebagai buku pegangan dasar oleh universitas-universitas di Eropa.&lt;/p&gt;&lt;p align="justify"&gt;Buku geografinya berjudul Kitab Surat-al-Ard yang memuat peta-peta dunia pun telah diterjemahkan kedalam bahasa Inggris. Buah pikir Khwarizmi di bidang geografi juga sangat mengagumkan. Dia tidak hanya merevisi pandangan Ptolemeus dalam geografi tapi malah memperbaiki beberapa bagiannya. Tujuh puluh orang geografer pernah bekerja dibawah kepemimpinan Al khwarizmi ketika membuat peta dunia pertama di tahun 830. Ia dikisahkan pernah pula menjalin kerjasama dengan Khalifah Mamun Al-Rashid ketika menjalankan proyek untuk mengetahui volume dan lingkar bumi. &lt;/p&gt;&lt;p align="justify"&gt;Sumber : &lt;a href="http://www.ilmukomputer.com/"&gt;http://www.ilmukomputer.com/&lt;/a&gt; &lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-3856963143248543965?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/3856963143248543965/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=3856963143248543965&amp;isPopup=true' title='0 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/3856963143248543965'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/3856963143248543965'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2008/03/asal-usul-kata-algoritma.html' title='Asal-usul kata Algoritma'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-8474032457066258895</id><published>2008-03-20T10:51:00.000-07:00</published><updated>2008-03-20T10:55:43.120-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Article'/><title type='text'>Greek Mathematics and its Modern Heirs</title><content type='html'>&lt;p&gt;Classical Roots of the Scientific Revolution&lt;/p&gt;&lt;div align="justify"&gt;For over a thousand years--from the fifth century B.C. to the fifth century A.D.--Greek mathematicians maintained a splendid tradition of work in the exact sciences: mathematics, astronomy, and related fields. Though the early synthesis of Euclid and some of the supremely brilliant works of Archimedes were known in the medieval west, this tradition really survived elsewhere. In Byzantium, the capital of the Greek-speaking Eastern empire, the original Greek texts were copied and preserved. In the Islamic world, in locales that ranged from Spain to Persia, the texts were studied in Arabic translations and fundamental new work was done. The Vatican Library has one of the richest collections in the world of the products of this tradition, in all its languages and forms. Both the manuscripts that the Vatican collected and the work done on them in Rome proved vital to the recovery of ancient science--which, in turn, laid the foundation for the Scientific Revolution of the 16th and 17th centuries. In the Roman Renaissance, science and humanistic scholarship were not only not enemies; they were natural allies.&lt;/div&gt;&lt;a href="http://www.ibiblio.org/expo/vatican.exhibit/exhibit/d-mathematics/images/math04.jpg"&gt;&lt;img style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 320px; CURSOR: hand" alt="" src="http://www.ibiblio.org/expo/vatican.exhibit/exhibit/d-mathematics/images/math04.jpg" border="0" /&gt;&lt;/a&gt; In Latin, 1458&lt;br /&gt;&lt;p align="justify"&gt;Euclid's "Optics" is the earliest surviving work on geometrical optics, and is generally found in Greek manuscripts along with elementary works on spherical astronomy. There were a number of medieval Latin translations, which became of new importance in the fifteenth century for the theory of linear perspective. This technique is beautifully illustrated here in the miniature of a street scene in this elegant manuscript from the library of the Duke of Urbino.

A number system with a base of 60 had developed in Babylon over time. Large numbers and fractions could be represented and formed the basis of advanced mathematical evolution. From at least 1700 BC, Pythagorean triples were studied. The study of linear and quadratic equations led to form of primitive numerical algebra. Meanwhile, similar figures, areas, and volumes were studied as well as the primitive values for pi obtained. The Greeks inherited the Babylonian principles and developed mathematics from 450 BC. They discovered that all real numbers could not accurately express all values, such as relationships between sides. Irrational numbers were born. The Greeks progressed rapidly in mathematics from 300 BC. Progress also sped in the Islamic countries of Syria, India, and Iran. Their work had a different focus from that of the Greeks, but all Greek principles held true. This basis was later brought to Europe and developed further there.&lt;/p&gt;&lt;p align="justify"&gt;Babylonians: Writing and Base 60 System&lt;/p&gt;&lt;p align="justify"&gt;The Babylonian system of writing was called cuneiform and was based on a series of straight lined symbols. These symbols were wet and baked in the hot sun to preserve. Curved lines could not be drawn. These cuneiform symbols led to many tables used to aid calculation. As stated previously, they used a base 60 system, which has ten proper divisors, instead of our current system, base 10 with only two proper divisors. In this respect, their system may have been more advanced since many more numbers have a finite form. Two examples of these tables are the tables found at Senkerah on the Euphrates River in 1854, which date from 2000 BC.

Recently, mathematician Daniel J. Madden and retired physicist, Lee W. Jacobi, found solutions to a puzzle that has been around for centuries.&lt;/div&gt;&lt;p align="justify"&gt;Jacobi and Madden have found a way to generate an infinite number of solutions for a puzzle known as 'Euler's Equation of degree four.'&lt;/p&gt;&lt;p align="justify"&gt;The equation is part of a branch of mathematics called number theory. Number theory deals with the properties of numbers and the way they relate to each other. It is filled with problems that can be likened to numerical puzzles.&lt;/p&gt;&lt;p align="justify"&gt;"It's like a puzzle: can you find four fourth powers that add up to another fourth power" Trying to answer that question is difficult because it is highly unlikely that someone would sit down and accidentally stumble upon something like that," said Madden, an associate professor of mathematics at The University of Arizona in Tucson.&lt;/p&gt;&lt;p align="justify"&gt;Equations are puzzles that need certain solutions "plugged into them" in order to create a statement that obeys the rules of logic.&lt;/p&gt;&lt;p align="justify"&gt;For example, think of the equation x + 2 = 4. Plugging "3" into the equation doesn't work, but if x = 2, then the equation is correct.&lt;/p&gt;&lt;p align="justify"&gt;In the mathematical puzzle that Jacobi and Madden worked on, the problem was finding variables that satisfy a Diophantine equation of order four. These equations are so named because they were first studied by the ancient Greek mathematician Diophantus, known as 'the father of algebra.'&lt;/p&gt;&lt;p align="justify"&gt;In its most simple version, the puzzle they were trying to solve is the equation: (a)(to the fourth power) + (b)(to the fourth power) + (c)(to the fourth power) + (d)(to the fourth power) = (a + b + c + d)(to the fourth power)&lt;/p&gt;&lt;p align="justify"&gt;That equation, expressed mathematically, is:  a4 + b4 +c4 +d4 = (a + b + c + d)4.&lt;/p&gt;&lt;p align="justify"&gt;Madden and Jacobi found a way to find the numbers to substitute, or plug in, for the a's, b's, c's and d's in the equation. All the solutions they have found so far are very large numbers.&lt;/p&gt;&lt;p align="justify"&gt;In 1772, Euler, one of the greatest mathematicians of all time, hypothesized that to satisfy equations with higher powers, there would need to be as many variables as that power. For example, a fourth order equation would need four different variables, like the equation above.&lt;/p&gt;&lt;p align="justify"&gt;Euler's hypothesis was disproved in 1987 by a Harvard graduate student named Noam Elkies. He found a case where only three variables were needed. Elkies solved the equation: (a)(to the fourth power) + (b)(to the fourth power) + (c)(to the fourth power) = e(to the fourth power), which shows only three variables are needed to create a variable that is a fourth power.&lt;/p&gt;&lt;p align="justify"&gt;Inspired by the accomplishments of the 22-year-old graduate student, Jacobi began working on mathematics as a hobby after he retired from the defense industry in 1989.&lt;/p&gt;&lt;p align="justify"&gt;Fortunately, this was not the first time he had dealt with Diophantine equations. He was familiar with them because they are commonly used in physics for calculations relating to string theory.&lt;/p&gt;&lt;p align="justify"&gt;Jacobi started searching for new solutions to the puzzle using methods he found in some number theory texts and academic papers.&lt;/p&gt;&lt;p align="justify"&gt;He used those resources and Mathematica, a computer program used for mathematical manipulations.&lt;/p&gt;&lt;p align="justify"&gt;Jacobi initially found a solution for which each of the variables was 200 digits long. This solution was different from the other 88 previously known solutions to this puzzle, so he knew he had found something important.&lt;/p&gt;&lt;p align="justify"&gt;Jacobi then showed the results to Madden. But Jacobi initially miscopied a variable from his Mathematica computer program, and so the results he showed Madden were incorrect.&lt;br /&gt;"&lt;/p&gt;&lt;p align="justify"&gt;The solution was wrong, but in an interesting way. It was close enough to make me want to see where the error occurred," Madden said.&lt;/p&gt;&lt;p align="justify"&gt;When they discovered that the solution was invalid only because of Jacobi's transcription error, they began collaborating to find more solutions.&lt;/p&gt;&lt;p align="justify"&gt;Madden and Jacobi used elliptic curves to generate new solutions. Each solution contains a seed for creating more solutions, which is much more efficient than previous methods used.&lt;/p&gt;&lt;p align="justify"&gt;In the past, people found new solutions by using computers to analyze huge amounts of data. That required a lot of computing time and power as the magnitude of the numbers soared.&lt;/p&gt;&lt;p align="justify"&gt;Now people can generate as many solutions as they wish. There are an infinite number of solutions to this problem, and Madden and Jacobi have found a way to find them all.&lt;/p&gt;&lt;p align="justify"&gt;"Modern number theory allowed me to see with more clarity the implications of his (Jacobi's) calculations," Madden said.&lt;/p&gt;&lt;p align="justify"&gt;"It was a nice collaboration," Jacobi said. "I have learned a certain amount of new things about number theory; how to think in terms of number theory, although sometimes I can be stubbornly algebraic."&lt;/p&gt;&lt;p align="justify"&gt;The article, ""On a4 + b4 +c4 +d4 = (a + b + c + d)4" is published in the March issue of The American Mathematical Monthly.&lt;/p&gt;&lt;p align="justify"&gt;Source : &lt;a href="http://www.sciencedaily.com/releases/2008/03/080314145039.htm"&gt;http://www.sciencedaily.com/releases/2008/03/080314145039.htm&lt;/a&gt;&lt;/p&gt;&lt;p align="justify"&gt;Rewrite by Kurnia&lt;/p&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-8356626019245383456?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/8356626019245383456/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=8356626019245383456&amp;isPopup=true' title='0 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/8356626019245383456'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/8356626019245383456'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2008/03/mathematicians-find-new-solutions-to.html' title='Mathematicians Find New Solutions To An Ancient Puzzle'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-8147576706784094632</id><published>2008-03-09T10:37:00.000-07:00</published><updated>2008-03-09T10:47:36.241-07:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='Curhat'/><title type='text'>Every Day with Recreational Math</title><content type='html'>&lt;div align="justify"&gt;May be that word is not macth on this time.

Di situs diceritakan mengenai riwayat hidup para matematikawan, sehingga diharapkan dapat meningkatkan minat para siswa untuk mendalami matematika.&lt;/div&gt;&lt;div align="justify"&gt; &lt;/div&gt;&lt;div align="justify"&gt;Selain itu, di dalamnya juga ada beberapa rubrik yang cukp menarik. Seperti rubrik ISENG-ISENG-ISENG yang membahas semua keajaiban angka dan dalam beberapa hal dikaitkan dengan mitologi. Rubrik AKSI SEL KELABU sebagai sarana asah otak (sel kelabu otak), menambah pemahaman, dianggap teka-teki, dan pada akhir halaman diberi jawaban; ASAL-ASALAN berisi latar-belakang atau kisah terciptanya konsep matematika yang sampai sekarang masih dipakai. Ketiga rubrik ini masing-masing sudah diisi dengan 40 topik yang sesuai dengan kategorinya dan akan terus ditambah. &lt;/div&gt;&lt;div align="justify"&gt; &lt;/div&gt;&lt;div align="justify"&gt;Ada rubrik CARI JODOH untuk orang yang mencari penghasilan tambahan dan murid yang perlu tambahan ilmu. Bagi yang terkadang bingung terdapat KAMUS UMUM yang berisi difinisi dari istilah-istilah yang dipakai. ABAM (Anda Bertanya, Anda Menjawab) dibuka sebagai sarana komunikasi antar komunitas. Siapa saja yang mengetahuinya dapat membagikan pengetahuannya kepada lainnya. Ilmu tidak habis jika dibagi, justru makin “bersarang” di otak.  Terakhir, adalah PENGGAGAS, yang menjadi “bapak” yang memerankan Tagachi yang selalu mencoba tampil paling beda. Tidak lupa dilengkapi dengan BUKU RUJUKAN apabila anda ingin mendalami lebih jauh.Visi yang ingin saya capai adalah “Matematika adalah topik yang menarik.”  Semua ini saya persembahkan demi pengembangan (pengetahuan) dan pemahaman yang merasuk, sehingga anak-anak tidak gugup, gagap  ataupun phobia dengan apa yang disebut matematika.&lt;/div&gt;&lt;div align="justify"&gt; &lt;/div&gt;&lt;div align="justify"&gt;Pokonya asyik dech kalo mengunjungi situs ini.

But kindergartners can solve math problems with large numbers long before they officially learn how to add and subtract. By using their instincts to estimate values, researchers report, kids can avoid the confusion of exact calculations.&lt;/div&gt;&lt;div&gt; &lt;/div&gt;&lt;div&gt;Psychologists from the University of Nottingham in England recently tested kids from a variety of backgrounds to make sure that wealth or level of education didn't get in the way of their results.&lt;/div&gt;&lt;br /&gt;&lt;div align="justify"&gt;&lt;/div&gt;&lt;img id="BLOGGER_PHOTO_ID_5151376113752477842" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="http://2.bp.blogspot.com/_SdqJVc93gs8/R31dSESmEJI/AAAAAAAAABg/kbJVvy0rFyc/s320/a1495_1255.row1.jpg" border="0" /&gt; &lt;p&gt;&lt;span style="font-size:78%;"&gt;&lt;/span&gt;&lt;/p&gt;&lt;p align="center"&gt;&lt;span style="font-size:78%;"&gt;In the new study, kids faced approximate-arithmetic problems involving addition, such as this one.&lt;br /&gt;Camilla K. Gilmore&lt;br /&gt;&lt;/p&gt;&lt;/span&gt;&lt;br /&gt;&lt;div align="justify"&gt;The first study involved 20 5- and 6-year-olds from wealthy, well-educated families. The kids sat in front of computers that showed a series of three-part math problems. One problem, for example, showed a girl's face in one box and a boy's face in another box. Above the girl's face was a bag labeled "21." Words on the screen read, "Sarah has 21 candies." &lt;/div&gt;&lt;div align="justify"&gt;&lt;br /&gt;The next screen showed a bag labeled "30" above the girl. Words read, "She gets 30 more." Finally, a bag marked "34" appeared above the boy. Words read, "John has 34 candies. Who has more?" &lt;/div&gt;&lt;div align="justify"&gt;&lt;br /&gt;Nearly three-quarters of kindergartners got the answer right. If the kids had just guessed who had more candies, only half of them would have been correct. &lt;/div&gt;&lt;div align="justify"&gt;&lt;br /&gt;In a second experiment, the scientists tested 37 kindergartners from poor and middle-class families. The kids had to answer questions in a hallway outside their public school classroom, meaning there were more distractions than in the first study. Still, almost two-thirds of these kids got the answers right. &lt;/div&gt;&lt;div align="justify"&gt; &lt;/div&gt;&lt;div align="justify"&gt;read &lt;em&gt;&lt;a href="http://www.sciencenewsforkids.org/articles/20070606/Note3.asp"&gt;more....&lt;/a&gt;&lt;/em&gt;&lt;/div&gt;&lt;div align="justify"&gt;&lt;em&gt;source from : &lt;a href="http://www.sciencenewsforkids.org/articles/20070606/Note3.asp"&gt;http://www.sciencenewsforkids.org/articles/20070606/Note3.asp&lt;/a&gt;&lt;/em&gt;&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/871184230529744867-4182021310440454251?l=kurnia25.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='replies' type='application/atom+xml' href='http://kurnia25.blogspot.com/feeds/4182021310440454251/comments/default' title='Poskan Komentar'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=871184230529744867&amp;postID=4182021310440454251&amp;isPopup=true' title='0 Komentar'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/4182021310440454251'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/871184230529744867/posts/default/4182021310440454251'/><link rel='alternate' type='text/html' href='http://kurnia25.blogspot.com/2008/01/math-naturals.html' title='Math Naturals'/><author><name>kurnia blog`s</name><uri>http://www.blogger.com/profile/17937851908144679419</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='http://img2.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media='http://search.yahoo.com/mrss/' url='http://2.bp.blogspot.com/_SdqJVc93gs8/R31dSESmEJI/AAAAAAAAABg/kbJVvy0rFyc/s72-c/a1495_1255.row1.jpg' height='72' width='72'/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-871184230529744867.post-1231619413097613372</id><published>2008-01-03T13:53:00.000-08:00</published><updated>2008-01-03T14:03:03.065-08:00</updated><category scheme='http://www.blogger.com/atom/ns#' term='CPNS'/><title type='text'>PENGUMUMAN PENDAFTARAN BAKAL CALON ANGGOTA BAWASLU</title><content type='html'>&lt;div align="justify"&gt;Dalam rangka melaksanakan Undang-undang Nomor 22 Tahun 2007 tentang Penyelenggara Pemilu, serta untuk mengisi calon anggota Badan Pengawas Pemilu (BAWASLU), Tim Seleksi Calon Anggota Bawaslu membuka pendaftaran calon Anggota Badan Pengawas Pemilu.&lt;/div&gt;&lt;div align="justify"&gt; &lt;/div&gt;&lt;div align="justify"&gt;Surat Lamaran, ditujukan kepada :Tim Seleksi Calon Anggota Bawaslud.a Sekretariat Tim Seleksi Calon Anggota BawasluJl.
