I'm a newbie in mathematica and I need something like a tutorial for Solving Laplace equation in Spherical coordinates (in my case: Steady temperature on a sphere) with Mathematica. As an example, I've found the exact tutorial for Maple software here:
Classroom Tips and Techniques: Eigenvalue Problems for ODEs - Part 2
At least please give me info about a place where mathematica tutorials are, or even a manual for solving partial differential equations in Mathematica.
