...The transformation into three-dimensional polar (or spherical) coordinates ( x , y , z ) → ( r ,θ,φ) is a curvilinear coordinate system that is indispensable for dealing with problems in mechanical systems with spherical symmetry, and is given by J ( r ,θ,φ)= r2sinθ . *Some of the terminology that refers to "moving coordinate system" is listed below.
