A Rapidly Converging Recursive Approach to Pi.

Peer reviewed

Dence, Joseph B.; Dence, Thomas P. – Mathematics Teacher, 1993

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)
