 * Math**

The Muslims invented the Arabic number system taht we use today. The Arabic system is superior to other methods for commerce, algebra, and simple math. Geometry as a mathematical science also owes a great deal to Islamic scholars, particularly in linking geometric and algebraic equations. Muslims also developed the experiemental method using hypothesis.

Al-Khwarizmi is recognized as the founder of modern Algebra. Al-Batani was the first mathematician to use the concept of sines and cotangents in the 9th century. Thabit Ibn Qurra studied conics, especially the parabola and ellipse, and helped develop an early form of calculus.

Mathematics: Muhammad ibn Musa al-Khwarizmi (780 AD) Thabit Ibn Qurra Abu Yunus Ghiyath al-Din al Kashani
 * He was the founder of Modern Algebra
 * Al-Khwarizmi also developed sine, cosine, and trigonometrically tables
 * He solved x ^2+21=10
 * Figured out the concept of zero
 * And amongst his many other achievements, Muhammad and a few of his colleagues were the first to map the globe
 * Established rules for manipulating algebraic expressions
 * Proved ax*bx-abx^2, a(bx)=(ab)x and (10-x)(10-x)=100+x^2-20x
 * Qurra also established x^nx^n=x^(m+n)
 * Proved cos(a)cos(b)=[cos(a+b)+cos(a-b)]/2
 * Wrote on how to approximate sin(1) by solving the cubic equation
