sage.calculus.desolvers: This file contains functions useful for solving differential equations
which occur commonly in a 1st semester differential equations course.
sage.calculus.test_sympy: A Sample Session using Sympy
In this first part, we do all of the examples in the Sympy
tutorial (\url{http://code.google.com/p/sympy/wiki/Tutorial}), but using
\sage instead of Sympy.
sage.calculus.wester: Further examples from Wester's paper
These are all the problems at
http://yacas.sourceforge.net/essaysmanual.html
They come from the 1994 paper "Review of CAS mathematical capabilities",
by Michael Wester, who put forward 123 problems that a reasonable computer
algebra system should be able to solve and tested the then current
versions of various commercial CAS on this list.
