"Visualizing Mathematics and Mathematical Processes" A.I. Weinzweig University of Illinois at Chicago 9711 N. Kildare Ave. Skokie, Illinois, 60076 USA E-mail:izzie@maverick.math.uic.edu We will present a number of examples of the use of Computer Algebra in helping students to understand some mathematical processes by "seeing" what happens. We will illustrate the solution of systems of linear equations by visulaizing the lines or planes generated at each step. We will illustrate the use of Taylor Series in approximating functions, and generating functions by Fourier Series. We will illustrate the use some interesting problems such as the coin rotating about a coin, or does any part of a railroad wheel go backwards, in motivating the study of curves and the use of trigonometry.
