Spherical longitudes
Spherical coordinates (r, θ, φ) as often used in mathematics: radial distance r, azimuthal angle θ, and polar angle φ. The meanings of θ and φ have been swapped compared to the physics convention. As in physics, ρ ( rho) is often used instead of r, to avoid confusion with the value r in cylindrical and 2D polar … See more 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 … See more To define a spherical coordinate system, one must choose two orthogonal directions, the zenith and the azimuth reference, and an … See more As the spherical coordinate system is only one of many three-dimensional coordinate systems, there exist equations for converting … 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 physics convention discussed.

These symbols, φ for latitude and λ for longitude, are unfortunate, but are often used in this context. In terms of the symbols θ , φ for spherical coordinates that we have used hitherto, the east longitude would correspond to φ and the latitude to 90 o − θ . A plane that intersects a sphere does so in a circle.
Webd is the distance between the two points along a great circle of the sphere (see spherical distance ), r is the radius of the sphere.
