Li Ye
1192 CE–1279 CE · Daxing (Beijing), China
Li Ye, born Li Zhi, was a Chinese mathematician of the Jin and early Yuan period who developed the tian yuan shu ('coefficient array') method for setting up and solving polynomial equations. His 1248 work Ceyuan haijing applied this algebra to geometry problems built around a circle inscribed in a right triangle. He changed his given name from Zhi to Ye to avoid confusion with the Tang emperor Li Zhi; he is that mathematician, not the Tang-era namesake. He spent his last years teaching near Fenglong Mountain in Hebei.
