Nice. Would you like to submit this as a patch to sympy? Probably create a new directory sympy/functions/coordinates, unless you have a better idea where to put this. I would rename CoordinateSystem3D to OrthogonalSystem3D, because that is what it is. Otherwise you'd have to use differential geometry, just like Alan has suggested. I also have some notes here how it works: http://certik.github.com/theoretical-physics/book/src/math/differential-geometry.html Ondrej --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
