Welcome to the SymPy wiki!
We encourage everyone to participate in this wiki. To edit it, you need to create an account (top right corner). Just fill in your name and password and that's it (no email confirmation, or other annoying things). Feel free to play/test something in the Sandbox.
Note, there are a bunch of pages in this wiki that are not linked to from here. See them all here.

SymPy is a computer algebra system (CAS) written in the Python programming language. SymPy is easy to use and install (see the download instructions and tutorial for more information), and works everywhere where Python 2.5 or newer is installed (Linux, Windows, Mac OS X, ...). SymPy's features include:
- Arbitrary precision integers, rationals and floats, as well as symbolic expressions
- Simplification (e.g. ( abb + 2bab ) → (3ab^2)), expansion (e.g. ((a+b)^2) → (a^2 + 2ab + b^2)), and other methods of rewriting expressions
- Functions (exp, log, sin, ...)
- Complex numbers (like
exp(I*x).expand(complex=True)→cos(x)+I*sin(x)) - Taylor (Laurent) series and limits
- Differentiation and integration
The main SymPy documentation is maintained at http://docs.sympy.org (where you can see both the development and the latest stable versions docs). The full change log can be viewed here.
The issue tracker is located at http://github.com/sympy/sympy/issues.

There are many pages copied here from the old Google code wiki. These should be updated and reformatted for github. They can be found by going here. and looking for the pages starting with "old wiki". When these are updated, the header should be changed and the file moved to remove the "old wiki" designation.
