The mathematical constant pi (π) has a long history of discovery across various cultures. Ancient Egyptians and Babylonians had approximations for pi, with values around 3.125. In ancient Greece, Archimedes used polygons to narrow down the value of pi to between 3.1429 and 3.1408. Chinese and Indian mathematicians also approximated pi, with values around 3.125 and 3.1416, respectively.In the modern era, calculus led to more accurate calculations of pi, with mathematicians like John Wallis, Isaac Newton, and Gottfried Wilhelm Leibniz contributing to improved methods. With the advent of computers, pi has been calculated to trillions of decimal places using various formulas and algorithms. The symbol π was first used by William Jones in 1706, derived from the Greek word "pi" (pronounced as "pee") and Latin words for perimeter and perimetron.
