37 1. Documentation and usage
38 --------------------------
42 http://code.google.com/p/sympy/wiki/Documentation
44 If you don't want to read that, here is a short usage:
46 From this directory, start python and:
47 >>> from sympy import Symbol, cos
50 >>> print e.series(x,10)
51 1 + (1/2)*x**2 + (5/24)*x**4 + (61/720)*x**6 + (277/8064)*x**8 + O(x**10)
53 SymPy also comes with a console that is a simple wrapper around the
54 classic python console (or ipython when available) that loads the
55 sympy namespace and defines three symbols: x, y, z.
61 from this directory if SymPy is not installed or simply
65 if SymPy is installed somewhere in your PATH.
75 in the current directory. You need to have py.test installed.
78 4. How to install py.test
79 -------------------------
81 If you use Debian, just install the python-codespeak-lib. Otherwise:
83 Execute in your home directory:
85 svn co http://codespeak.net/svn/py/dist py-dist
87 This will create a "py-dist" directory in you home dir. Add this line to
90 eval `python ~/py-dist/py/env.py`
92 Now you can call "py.test" from anywhere.
97 To clean everything (thus getting the same tree as in the svn):
105 SymPy was started by Ondrej Certik in 2005, he wrote some code during the
106 summer, then he wrote some more code during the summer 2006. In February 2007,
107 Fabian Seoane joined the project and helped fixed many things, contributed
108 documentation and made it alive again. 5 students improved SymPy incredibly
109 during the summer 2007 as part of the Google Summer of Code. Pearu Peterson
110 joined the development during the summer 2007 and he has made SymPy much more
111 competitive by rewriting the core from scratch, that has made it from 10x to
