How can I plot equations in coordinates other than Cartesian coordinate easily. In Mathematica 6, new commands are supported such as PolarPlot and SphericalPlot and so on; my question is can I plot a 3D graph in spherical coordinate without SpherialPlot, and if I want to plot a graph in Maxwell coordinate directly which command should I use if I don't want to make a coordinate transformation? P.S., I find that many calculations in Mathematica are much faster than those in other computing algebra system, whether the difference comes from those codes used in Mathematica calculations are kernel functions( i.e. DSolve) and compiled in C, but in others not (maybe written in their languages)? Thanks for your reply.
