2.. Consider the transformation to spherical coordinates: (r, q, j) where r is the polar coordinate, q Is the polar coordinate with respect to the z axis, and f is the azimuth angle measured from the x axis to the projection of r 1vector onto the xy plane of a rectangular Cartesian Coordinate system: The transformation is: Xx = r sin(q) cos(f) Yy = r sin(q) sin(f) Z: = r cos(q)
