This update of Jerry Glynn and Theodore Gray's hugely successful textbook covers not only the basic Mathematica features, but also the new features of Mathematica Version 4. The book teaches new Mathematica users some of the important basics of the latest release of this powerful software tool: using the typesetting features, programming palettes, defining functions, creating graphs and notebooks, and applying useful problem solving techniques. Using their skills as Mathematica experts and teachers, the authors provide a brisk but careful tutorial for the Mathematica novice. From the fundamentals of installing and running Mathematica on your computer, through to tips on how to get the most from the advanced programming features, the presentation maintains its concise and knowledgeable tone, providing indexes for both concepts and Mathematica function names. This book will be a valuable tool for both students and individual Mathematica users.
