## cylindrical coordinatesA coordinate system in which a point is located by its height z
above a reference plane and the polar
coordinates of its projection onto that plane, (r, θ).
(r, θ, z) can be related to rectangular
Cartesian coordinates by x = r cosθ,
y = r sinθ, and z = z
(where the original reference plane corresponds to the xy-plane).
