1 article for "Cartesian Coordinates"

Rectangular Cartesian Coordinates locate a point relative to a set of intersecting mutually perpendicular straight lines. The coordinates of a point are given by (x,y,z). Any point can be located by finding its perpendicular distance from each of the axes. In a two dimensional plane it takes two coordinates to pin down a point exactly; in three dimensional space it takes three; and so on. The simplest example of Cartesian coordinates is a city map, in which a place may be located by specifying its street and avenue. The coordinates need not correspond to actual spatial distances but can be times or any other quantities.
