Jabarkan Omar Khayyam dari Matematik pada zaman pertengahan Islam dalam bahasa melayu

The Persian poet Omar Khayyam (b. 1048) was also a mathematician, and wrote Discussions of the Difficulties in Euclid, a book about flaws in Euclid's Elements. He gave a geometric solution to cubic equations, one of the most original discoveries in Islamic mathematics. He was also very influential in calendar reform. He also wrote influential work on Euclid's parallel postulate.

Omar Khayyam gave a complete classification of cubic equations with geometric solutions found by means of intersecting conic sections. Khayyam also wrote that he hoped to give a full description of the algebraic solution of cubic equations in a later work:

"If the opportunity arises and I can succeed, I shall give all these fourteen forms with all their branches and cases, and how to distinguish whatever is possible or impossible so that a paper, containing elements which are greatly useful in this art will be prepared."

The Indo-Arabic system of calculating also allowed the extraction of roots by Omar Khayyam. Omar Khayyam also combined the use of trigonometry and approximation theory to provide methods of solving algebraic equations by geometrical means.
