 and to that of finite differences. His two mathematical works, Introduction to Mathematical Studies and Precious Mirror of the Four Elements, were lost for a time in China and were recovered only in the 19th cent.

Chu Shih-Chieh

 

Chinese mathematician of the 13th century. In his treatise Precious Mirror of the Four Elements, Chu described a method for solving numerical equations similar to Horner’s method and presented methods for forming equations. Chu developed a notation for equations of higher degree in four unknowns and solved a number of problems that reduce to such equations.
