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. Go to _pages to see them all.

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://code.google.com/p/sympy/issues/list.
The best place to begin is the Tutorial. A lot of useful information can also be found in the following:
- FAQ -- Frequently Asked Questions about SymPy
- Quick examples -- This page shows example commands for doing common calculations in SymPy
- Cookbook -- Various recipes
- Presentations -- Slides, tutorials and posters from conferences
- Comparison to popular CAS's -- Axiom, Magma, Maple, Mathematica, Matlab, Maxima, Sage, Yacas
- Roadmap -- Our roadmap to SymPy 1.0
- Ideas -- Random ideas, not necessarily related to SymPy, but that could be useful for SymPy in the future
- Generic interface -- SymPy/SymPyCore design notes
- Technical References -- Related mathematical literature and websites
- Test automation -- Wishlist scratchpad for streamlining the test suite
- Unit systems -- Some ideas to improve unit systems.

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 to _pages 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.
Unless stated otherwise, everything on this wiki is licensed under the same terms as SymPy, i.e. [[modified BSD|http://www.opensource.org/licenses/bsd-license.php]] license. This is so that we can take anything from here and add it to the SymPy tarball as a documentation. See License choice for the motivation and discussion behind that choice.
If you have some interesting material, that you don't want to (or cannot) make BSD licensed, please put there a notice, that it has some other license.
