The 18 pages that link to Spherical coordinate system, each with the reason it gives.

• SphereRelated: Its radial coordinate makes the sphere a constant-radius surface.

• Solid angleRelated: Its angular area element provides a direct way to integrate solid angles.

• RadiusRelated: Its radial coordinate generalizes circle-centered distance to three dimensions.

• Spherical symmetryRelated: They separate the radial dependence from angular directions in symmetric problems.

• Coordinate singularityRelated: Its angular coordinates fail at the poles, where multiple coordinate pairs describe the same point.

• Unit sphereRelated: Fixing the radial coordinate at one parametrizes the unit sphere.

• SteradianRelated: The angular coordinates describe directions whose measure is expressed in steradians.

• Volume integralRelated: Its volume element fits spherical regions and radial symmetry.

• 3-sphereRelated: Three angular parameters describe points on a 3-sphere after fixing the radius.

• Square degreeRelated: Angular coordinate patches define the regions whose areas can be reported in square degrees.

• Hyperspherical methodRelated: The hyperspherical construction generalizes this radial-and-angular split to higher dimensions.

• Zonal and meridional flowRelated: Earth’s latitude–longitude grid supplies the directional frame for these components.
