-Giac is a free computer algebra system that can be used to perform
-computer algebra, function graphs, interactive geometry (2-d and 3-d),
-spreadsheet and statistics, programmation. It may be used as a replacement
-for high end graphic calculators for example on netbooks (for about
-the same price as a calculator but with much more performances).
