Further, it is customizable to your desires, that is the language is extensible. Is it easy to use? It depends on your viewpoint. Mma (my shorthand for Mathematica) is a computer algebra system that does algebra far better than I can, and without error. From my viewpoint it is a pleasure to have a strong algebra program do my dirty work. Is that fun and easy, you bet. As I understand the current student version, it is the same as the professional version. In the past the major difference was in the use of the math co-processor but today they are the same. I use the professional version under Win95 and on a NeXT. The student version comes with an abbreviated text (the Mma text is 1400 pages long, and well worth it) plus about 500 to 600 pages of support packages (application specific). Using Mma will make you a better scientist or engineer and the envy of your associates who try to keep up with manual algebra. I have taught Mma for the last six years in a combined grad and undergrad course called Numerical Methods with Mma. It is a tough course but well worth the effort. sincerely sherman reed Bell-Labs, retired UTA, EE, retired
