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)

Waits, Bert K.; Demana, Franklin – Mathematics Teacher, 1988
Argues that the college preparatory curriculum should include more than three years of mathematics. Presents data indicating that 86 percent of students with less than three years of college preparatory mathematics take remedial mathematics and relatively few students are ready to take calculus when they enter the university. (PK)

Waits, Bert K.; Demana, Franklin – Mathematics Teacher, 1992
Presented are two reasons discouraging computer symbol manipulation systems use in school mathematics at present: cost for computer laboratories or expensive pocket computers; and impracticality of exact solution representations. Although development with this technology in mathematics education advances, graphing calculators are recommended to…
