I've searched everyone and I can not seem to find anything that illustrates an example of how to convert a Cartesian Vector with a specified origin into Spherical coordinates.
I know how to convert a Cartesian Vector into Spherical coordinates when the origin is 000, but I don't know what to do when it is not.
For Instance, If given a V_(3,4,-5) with origin (3,4,5) how would I convert with the origin in mind? I know that the spherical coordinates are calculated as follow:
r=sqrt((V_x^2)+(V_y^2)+(V_z^2))
theta=inverse cos (V_z/sqrt((V_x^2)+(V_y^2)+(V_z^2)))
phi=arctan(V_y^2/V_x^2)
but then what would I do next? Any help?
