Web10 jan. 2024 · Spherical coordinates are useful in analyzing systems that are symmetrical about a point. For example a sphere that has the cartesian equation has the very simple equation in spherical coordinates. Spherical coordinates are the natural coordinates for physical situations where there is spherical symmetry (e.g. atoms).
