单词 | Cartesian coordinates |
释义 | Cartesian coordinates In mathematics, any of the coordinates that locate a point on a plane and meas- ure its distance from an axis at which two or more planes intersect. Such a point is identified by its position relative to the x-axis (horizontal) and y-axis (vertical) in a two-dimensional grid, chart, or graph, or by its position relative to the x-axis, y-axis, and z-axis (depth) in a three-dimensional grid, chart, or graph. The underlying mathematical concepts were developed by René Descartes, the Latin form of whose name is Cartesius. See also x-axis, y-axis, and z-axis. |
