It is more important for children to learn concepts in mathematics than to be able to perform automatic computational functions. By permitting manipulation of the relationships among visible objects, computer graphics can make it easier for students to grasp concepts and can serve as an essential ingredient in effective computer-assisted…

Describes a graphical method of approximating roots of complex functions that uses the multicolor display capabilities of microcomputers. Theorems and proofs are presented that illustrate the method, and uses in undergraduate mathematics courses are suggested, including numerical analysis and complex variables. (six references) (LRW)
