A previously developed program for the HP-41C programmable calculator is extended to handle models of differential and difference equations with multiple eigenvalues. How to obtain difference equation solutions via the Z transform is described. (MNS)

Presented is a program written for an HP-25 programmable calculator. It will aid in the effective impedance of a series-parallel network containing both reactive and resistive elements. (MNS)

Describes a program written for a programmable pocket calculator that computes the frequency response of linear systems. (Author)

Discusses numerical methods to compute approximate solutions of a differential equation. Provides a Pascal program for the extended Euler-Heun method. (YP)

Strategies for incorporating a calculator made within FORTRAN programs and a Response Analysis Scheme during interactive sessions are described highlighting salient features of the programs. (Author/SK)

A mathematics course using programmable calculators, which was part of a summer enrichment program for upper elementary and junior high students, is described. (MK)

This article discusses the impact of symbolic-manipulation systems on secondary school mathematics curriculum. Characteristics and possible roles for the symbolic systems are explored. Four references are listed. (YP)

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)

This three-part volume provides a summary, for use by practitioners, of a project concerned with how novices learn to become creative educational computer users. The first chapter examines techniques for increasing the novice's understanding of computers and computer programming, and specifically analyzes the potential usefulness of five…

This Texas Tech University computer literacy course designed for preservice elementary and middle school mathematics teachers lacking a technological orientation facilitates their computer introduction through preliminary use of calculators. Course development, philosophy, and course segments are outlined with emphasis on the sequence in which…
