MacMath is a scientific toolkit for the Macintosh computer consisting of 12 graphics programs. It supports mathematical computation and experimentation in dynamical systems, both for differential equations and for iteration. MacMath addresses differential equations and iteration such as: analyser, diffeq, phase plane, diffeq 3D views, numerical methods, periodic differential equations, cascade, 2D iteration, eigenfinder, jacobidraw, fourier, planets. These versatile programs greatly enhance the understanding of the mathematics in these topics. This new edition includes the latest version of the MacMath diskette, 9.2.
