You might wish to be more general and implement vector analysis as a
function of a metric tensor. See the following link -

Lukas,
Sachin Joglekar developed the vector package this past summer. I
was his GSoC mentor on the project. You can check out this
implemented of the Cartesian coordinate system:
https://github.com/sympy/sympy/blob/master/sympy/vector/coordsysrect.py
<https://github.com/sympy/sympy/blob/master/sympy/vector/coordsysrect.py>
You'd basically need to create a class for spherical that has this
same functionality. You may be able to create a spherical class
that converts the input to Cartesian and just manages a Cartesian
system behind the scenes. Or method can be implemented explicitly
using spherical coordinates.

Hi everyone,
I am Lukas from Chile, pursuing a degree in Computer Science
and with interests in mathematics. I would like to start
contributing to sympy. Reading through the mailing list, I saw
this
<https://groups.google.com/forum/?hl=es-419#%21topic/sympy/4SIr_6iW6v4>post
that says that the Spherical Coordinates System isn't
implemented yet, so I would like to start from there. I wanted
to know who can I ask to give me further information about
this specific functionality, or things I need to know before
implementing this (not about the theory, but about the
concrete implementation of the spherical system in the vector
module).
Thanks :)!
Lukas
