Arab's Contribution to Mathematics: Hua Lazimi, a mathematician with a prickly submodule, developed algebra into an independent branch of mathematics. His Reduction and Object Science became a masterpiece in the history of mathematics, and he himself was also called the father of algebra. His works were textbooks of major universities in Europe in the16th century. Other Arab mathematicians have made great achievements in trigonometry. They developed trigonometry into an independent discipline, and calculated pi to 17 digits, breaking the record of 1000 kept by China mathematician Zu Chongzhi. In geometry, they linked figures with algebraic equations and became pioneers in analytic geometry. Later, Descartes' analytic geometry was also realized on the basis of Arabs. The greatest contribution of Arabs to science is to develop perfect algebra by using Arabic numerals as tools and combining the logic of ancient Greece. Today, the word "algebra" comes from Arabic (JABR). Omar khayyam, a Persian, is the author of Argument of Algebraic Problems (hereinafter referred to as Algebra) and one of the most outstanding figures in the history of mathematics, especially algebra. In addition, omar khayyam further developed the binomial theorem.

Trigonometry plays an important role in Arabic mathematics, and its emergence and development are closely related to astronomy. Arabs developed trigonometry on the basis of the work of Indians and Greeks. They introduced several new trigonometric quantities, revealed their properties and relationships, and established some important trigonometric identities. All the solutions of spherical triangle and plane triangle are given, and many accurate trigonometric function tables are made. /kloc-Nasir-Ud-deen, a scholar in the 3rd century, wrote a book about trigonometry systematically and completely, which made trigonometry break away from astronomy and become an independent branch of mathematics, which had a great influence on the development of trigonometry in Europe.
