Who is the French philosopher credited with the invention of analytic geometry?

René Descartes is credited with inventing analytic geometry in the 17th century. His revolutionary approach combined algebra and geometry by representing geometric shapes with equations and introducing the Cartesian coordinate system (x-y plane). This allowed geometric problems to be solved using algebraic methods and vice versa. Archimedes was ancient Greek, John Napier invented logarithms, and Georg Cantor worked on set theory much later.
