Jonathan Knights,Murali Ramanathane systems may prove more useful in trying to solve certain mechanics problems. In the following three recipes, we illustrate kinematics in plane polar and spherical polar coordinates and how to generate “scale factors” for calculating area and volume elements, gradients, Laplacians, etc., in toroidal coordinates.

IntroductionASs not only allow one to carry out the numerical computations of standard programming languages, but to also perform complicated symbolic manipulations as well. The purpose of this text is to show how a CAS can be used to breathe new life into a venerable subject, classical mechanics, by introducin
