Consider a cartesian, a cylindrical, and a spherical coordinate system, related as shown in Figure 1.
Figure 1: Standard relations between cartesian, cylindrical, and spherical coordinate systems. The origin is the same for all three. The positive z-axes of the cartesian and cylindrical systems coincide with the positive polar axis of the spherical system. The initial rays of the cylindrical and spherical systems coincide with the positive x-axis of the cartesian system, and the rays =90° coincide with the positive y-axis.
Then the cartesian coordinates (x,y,z), the cylindrical coordinates (r,,z), and the spherical coordinates (,,) of a point are related as follows:
