The following illustrations show a point P in different three-dimensional coordinate systems:

The Cartesian, or rectangular, coordinate system is the most widely used coordinate system. The cylindrical coordinate system is a generalization of two-dimensional polar coordinates to three dimensions. The following equations describe the relationship between a Cartesian coordinate and a cylindrical coordinate:

x = ρ · cosθ, y = ρ · sinθ, z = z

ρ is the radial coordinate, and θ (–π < θ ≤ π) is the azimuthal coordinate.

The spherical coordinate system is a system of curvilinear coordinates that is natural for describing positions on a sphere. The following equations describe the relationship between a Cartesian coordinate and a spherical coordinate:

x = r · sinϕ · cosθ, y = r · sinθ · sinϕ, z = r · cosϕ

r is the distance from point P to the origin. θ (–π < θ ≤ π) is the azimuthal angle, and ϕ (0 ≤ ϕ ≤ π) is the polar angle.
