Descartes is a famous and well noted European mathematician who lived hundreds of years ago. He pioneered many of the complex math procedures, equations, and mathematical form â¦ ulas that we still use today. Descartes is the namesake of the standard Cartesian or rectangular coordinate system. He also is famous for saying I think, therefore I am. Descartes' theory provided the basis for the calculus of Newton and Leibniz, by applying infinitesimal calculus to the tangent line problem, thus permitting the evolution of that branch of modern mathematics.
