Discusses the role of computers in mathematics education, including their use (computer science) as a subject area and as a means of delivering instruction. Indicates that the computer challenge is here but the mathematics education system has yet to rise to the challenge. (JN)

Some insights are provided into techniques for removing the mystery of how calculators evaluate functions. (Author/MK)

Presents an algorithm to estimate pi by approximating a unit circle with a sequence of inscribed regular polygons. Demonstrates the application of the algorithm with a hand-held calculator and an Apple computer. Provides a program to calculate pi in Pascal programing language. (12 references) (MDH)

Examples of composite functions present students with intriguing questions that they can explore using calculators and computers, geometric and algebraic methods, and approximation techniques. Student-centered activities allow students to make discoveries about functions. (MLN)
