COORDINATE GEOMETRY

Divide each diculty into as many parts as is feasible and necessary to resolve it. - Rene Descartes The French Mathematician Rene Descartes (pronounced “DAY- CART”) developed a new branch of Mathematics known as Analytical Geometry or Coordinate Geometry which combined all arithmetic, algebra and geometry of the past ages in a single technique of visualising as points on a graph and equations as geometrical shapes. The fixing of a point position in the plane by assigning two numbers, coordinates, giving its distance from two lines perpendicular to each other, was entirely Descartes’ invention.
