There was a lengthy review of Mathcad in the 12/92 CACM. Symbolic/numeric experimentation can help explain wavelet theory, image filters, or neural-network squashing functions. J.M. Jagadeesh says that the $395 Mathcad 3.1 for Windows has a superb user interface and adequate symbolic processing capabilities, but is not as powerful as Maple. Future reviews may cover Axiom, Derive, Macsyma, Mathematica, and Theorist. [The Mac version lists for $495, but the company keeps sending me "non-transferable" discount offers of any Mathcad version for just $88.95, including S&H. (800) 289-5075.]
