Sage (http://sagemath.org/) is a free open-source mathematics software system licensed under the GPL. It combines the power of many existing open-source packages into a common Python-based interface.
This tutorial will present some of the capabilities of Sage for doing mathematical computations. To attend this tutorial, no particular knowledge in mathematics is required. You are only required to be fluent in Python, and to have Sage installed and running on your computer, so that integrate(2sin(x)exp(x),x,0,pi) gives e^pi + 1.
This tutorial will be partly based on examples of the book (in french) on Sage available at http://sagebook.gforge.inria.fr/.
Note: a coding-sprint session will be organized on Sunday 25 August, for those who are interested to learn more about Sage, and/or to contribute to Sage.
