Pi Approximation Day occurs every July 22nd. It celebrates pi, a key mathematical constant. Pi relates a circle's circumference to its diameter. William Jones introduced the π symbol in 1706.

If the initial approximation to the zero, for f (x) f (x) given above, is x1, x 1, what formula does Newton's method give for the next approximation? The root of the equation f (x)= 0 f (x) = 0 is x = ...

This interactive feature illustrates Archimedes' basic approach to calculating pi. It finds an approximation by determining the length of the perimeter of a polygon inscribed within a circle and ...
