High-Resolution Plots of Trigonometric Functions.
Peer reviewed Peer reviewed
Stick, Marvin E.; Stick, Michael J. – Mathematics Teacher, 1985
Provides computer programs (for Apple microcomputers) for drawing (in high resolution graphics) a three-leaved rose, concentric circles, circumscribed and inscribed astroids. Sample output and discussions of the mathematics involved in the programs are included. (JN)

Animated Circular Functions with a Microcomputer.
Peer reviewed Peer reviewed
Hermann, James P. – Mathematics Teacher, 1988
Argues that students should have dynamic perceptual experience with the concepts central to circular functions. Includes a computer program, designed for Apple II, to provide such experience. (PK)

Finding Points of Intersection of Polar-Coordinate Graphs.
Peer reviewed Peer reviewed
Esty, Warren W. – Mathematics Teacher, 1991
In polar coordinates, the intersection of the graphs of two functions, f(x) and g(x), does not always correspond to the solutions of the equation f(x) = g(x). Presented are examples to illustrate this concept, proofs demonstrating why this is true, and a computer program to simultaneously plot polar coordinate graphs. (MDH)

Graphics Software Side by Side.
Peer reviewed Peer reviewed
DiFazio, Martha Hunt – Mathematics Teacher, 1990
Suggested are features which should be considered before selecting a specific interactive graphics package. Features that allow for accurate estimates of roots of functions and solutions to systems of equations are illustrated. Six graphics packages are compared including display, tabular options, misleading graphics, printing options, functions…

A Teacher's Exploration of Personal Computer Animation for the Mathematics Classroom.
Peer reviewed Peer reviewed
Kaljumagi, Eric A. – Journal of Computers in Mathematics and Science Teaching, 1992
Presents the results of a preliminary investigation into the feasibility of teachers constructing their own animations for the mathematics classroom using computer animation tools. Provides examples of animation constructed using "Ani ST" and "Mathematica" programs. Concludes that computer animation has potential to be a…
