In the 1600s a French mathematician and philosopher discovered the most important tool for our unit of graphing and plotting points, the coordinate plane Prior to this invention, a geometric figure would be created and the parts of it would be defined from it With the discovery of the "Cartesian Plane," Rene Des Carte could define or describe things prior to the figure being established.
Most of Des Carte's work can be located in three of his books He felt that only mathematics was certain, so all in the world must be based on mathematics In La Dioptrique, Des Carte studies optics This book did not discuss anything new, it experimented with past beliefs Another book Les Meteores is a book on meteorology It is the first book to study weather as a science, although many of his conjectures were inaccurate The most important book we would like to look at is La Geometrie Within this book Des Carte wrote about:
1.
|
The first step toward invariants.
|
2.
|
Recognition of Geometry through Algebra.
|
3.
|
Importing Algebra into Geometry.
|
4.
|
How we can solve many previously unsolved Geometric problems using Algebra.
