La Géométrie connects curves with equations
Descartes used algebraic operations to investigate geometrical problems, helping connect curves with equations.

The story
Published in Leiden as an essay accompanying the Discourse on Method, La Géométrie developed algebraic approaches to constructions and curves. It built on earlier algebra and geometry; Fermat independently developed related methods. The book did not contain the complete Cartesian-coordinate presentation familiar from modern classrooms, and later notation should not all be assigned to 1637.
Connections and context
Equations made curves easier to compare and helped prepare tools for calculus and physical modelling.
