In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuthal angle of its orthogonal … See more To define a spherical coordinate system, one must choose two orthogonal directions, the zenith and the azimuth reference, and an origin point in space. These choices determine a reference plane that contains … See more Just as the two-dimensional Cartesian coordinate system is useful on the plane, a two-dimensional spherical coordinate system is useful on the surface of a sphere. In this system, the sphere is taken as a unit sphere, so the radius is unity and can generally be … See more The following equations (Iyanaga 1977) assume that the colatitude θ is the inclination from the z (polar) axis (ambiguous since x, y, and z are mutually normal), as in the … See more In spherical coordinates, the position of a point or particle (although better written as a triple$${\displaystyle (r,\theta ,\varphi )}$$) can be written as $${\displaystyle \mathbf {r} =r\mathbf {\hat {r}} .}$$ Its velocity is then See more As the spherical coordinate system is only one of many three-dimensional coordinate systems, there exist equations for converting … See more It is also possible to deal with ellipsoids in Cartesian coordinates by using a modified version of the spherical coordinates.
