spherical coordinate system
- spherical coordinate system
-
In geometry, a
coordinate system in which any point in three-dimensional space is specified by its angle with respect to a polar axis and angle of rotation with respect to a prime meridian on a sphere of a given radius.
In spherical coordinates a point is specified by the triplet (r, θ, φ),
where r is the point's distance from the origin (the
radius), θ is the angle of rotation from the initial meridian plane, and φ is the angle from the polar axis (analogous to a ray from the origin through the North Pole).
