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 2.7 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 (grouping like
a*b*b + 2*b*a*b→
3*a*b**2, expansion like
expand((a + b)**2)→
a**2 + 2*a*b + b**2, and other methods of rewriting expressions (
- Functions (
- Complex numbers (like
- Taylor (Laurent) series and limits
- Differentiation and integration
