Spherical Coordinates
 |
|
Spherical coordinates are a coordinate system in which points in three-dimensional space are given by two angles and a distance from the origin.
Spherical coordinates is a high school-level concept that would be first encountered in a pre-calculus course.
Prerequisites
| Cartesian Coordinates: | 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. |
| Polar Coordinates: | Polar coordinates are a two-dimensional coordinate system in which points in two dimensions are given by an angle and a distance from the origin. |
| Sphere: | A sphere is the set of all points in three-dimensional space that are located at a fixed distance from a given point. |
