This section provides an overview of what sympy is, and why a developer might want to use it.
It should also mention any large subjects within sympy, and link out to the related topics. Since the Documentation for sympy is new, you may need to create initial versions of those related topics.
As of version 1.0 of Sympy perhaps the main thing to understand about using its solvers is that 'solveset will take over solve either internally or externally'. At this point solveset should already be used for solving univariate equations and systems of linear equations.
