Around the Sun in a Graphing Calculator.

Peer reviewed

Demana, Franklin; Waits, Bert K. – Mathematics Teacher, 1989

Discusses the use of graphing calculators for polar and parametric equations. Presents eight lines of the program for the graph of a parametric equation and 11 lines of the program for a graph of a polar equation. Illustrates the application of the programs for planetary motion and free-fall motion. (YP)

Fractals Illustrate the Mathematical Way of Thinking.

Peer reviewed

Nievergelt, Yves – College Mathematics Journal, 1991

Presented are exercises that demonstrate the application of standard concepts in the design of algorithms for plotting certain fractals. The exercises can be used in any course that explains the concepts of bounded or unbounded planar sets and may serve as an application in a course on complex analysis. (KR)
