Cartesian coordinates are a coordinate system that represents points in space using ordered pairs or triples of real numbers. In two-dimensional space, Cartesian coordinates consist of an x-coordinate and a y-coordinate, while in three-dimensional space, they include an x-coordinate, a y-coordinate, and a z-coordinate. The Cartesian coordinate system is named after the French mathematician René Descartes, who developed the system in the 17th century.
Cartesian coordinates are widely used in mathematics, physics, engineering, and other fields to describe the position of points, lines, and surfaces in space. They provide a simple and intuitive way to represent geometric objects and perform calculations. Cartesian coordinates can be converted to other coordinate systems, such as cylindrical coordinates or spherical coordinates, depending on the problem at hand.
