Omar Khayyam (1048–1131) was a Persian poet and polymath, known for his contributions to mathematics, astronomy, philosophy, and Persian literature. He was born in Nishapur, Iran and lived during the Seljuk era, around the time of the First Crusade. As a mathematician, Omar Khayyam was the first to provide a general solution for all third-degree polynomials by using the intersection of two conic sections, a method often later attributed to Descartes. Unlike Descartes, Khayyam performed these geometric calculations by selecting a unit length while strictly adhering to the rule of homogeneity. Additionally, in his work On the Division of a Quarter of a Circle, he attempted to derive approximate numerical solutions for cubic equations using trigonometric tables.
