If you are doing geometric calculations you should look at section 10.2.2, _Conformal Model of Euclidean Space_ in "Geometric Algebra for Physicists" by Doran & Lasenby. Their methods greatly simplify the calculation of geometric transformations and the intersections of lines, planes, circles

By the way, for the Google Code projects, click on "source" and type "sympy" into the "Search Trunk" field to get an idea of how they use it. I don't know if there's an easy way to do that with GitHub (other than cloning and "git grep sympy"). Aaron Meurer On Mon, May 16, 2011 at 12:52 AM, Aaron

Cool. Does your university use SymPy, or is it just something that you personally use? And by the way, even if you're not from a developing country, you can save a lot of money by using open source software (assuming it is of comparable quality). Aaron Meurer On Thu, May 12, 2011 at 7:16 PM, li
