Cartesian Coordinates

Explore CartesianCoordinates on MathWorld


Cartesian coordinates are the usual coordinate system, originally described by Descartes, in which points are specified as distances to a set of perpendicular axes. Also called rectangular coordinates.

Cartesian coordinates is an elementary-school-level concept. It is listed in the California State Standards for Grade 4.

Examples

Complex Plane: The complex plane is a term for the set of all complex numbers. Just as all real numbers can be imagined as lying on a line, all complex numbers can be thought of as points in a plane.

Prerequisites

Line: A line is the infinite extension in both directions of a line segment, giving the path of shortest distance between two points in Euclidean space.
Plane: A plane is a two-dimensional surface defined by linear equations.
