  2. A free reader for Mathematica, MathReader, is also available. You can view and run previously generated workbooks, but can't create new one ones. After you download the reader, go visit their library of resources and tutorials.
  3. A web-based front end for Mathematica computations can be seen here
Computer Algebra Systems
  1. A free downloadable version of Maple V R4 ( mvr4demo.exe) is available from Waterloo Software here . Bear in mind that it only implements a subset of Maple commands, and does not (for example) allow you to define procedures. Nevertheless, as far as demonstrating the capabilities of Maple it is good.
  2. MuPad is no longer a separate CAS package. It has been acquired by MathWorks (ie MatLab) to replace Maple as their internal symbolic engine.
  3. A free 30-day version of Maple 15 for Windows can be found here .
  4. You can get a free 30 day trial for MatLab. Fill out the required information to request the 30-day trial version. Unfortunately, it is no longer available to students....
