PI Approximator Applet

The German mathematician Gottfried Leibniz developed the following method to approximate the value of π.

The formula is based on an infinite series derived from higher mathematics.

Formula: π/4 = 1 - 1/3 + 1/5 - 1/7 + ...

This could be transposed algebraically to π = 4 x (1 - 1/3 + 1/5 - 1/7 + ...)

This program will allow the user to compute π to a specified number of terms of the infinite series.
