## History of Pi

The history of pi dates back thousands of years, with ancient civilizations approximating its value for practical computations . Here’s a brief overview:

**Pre-Common Era:**The earliest written approximations of pi were found in Babylon and Egypt, with values accurate to two decimal places (3.125 and 3.1605, respectively).**250 BC:**The Greek mathematician Archimedes developed a geometrical approach using polygons to calculate pi, approximating its value as 3.1418 (223/71 < pi < 22/7). This method, known as the “method of exhaustion,” dominated for over 1,000 years.**150 AD:**Ptolemy, a Greek-Roman scientist, approximated pi as 3.1416, possibly drawing from Archimedes’ work.- 5th century AD: Chinese mathematicians approximated pi to seven digits (3.1415926), while Indian mathematicians achieved a five-digit approximation (3.14156).
**16th-17th centuries:**The development of infinite series techniques revolutionized pi calculations. Mathematicians like James Gregory, Gottfried Wilhelm Leibniz, and Madhava of Sangamagrama (who estimated pi to 11 digits around 1400) made significant contributions.**1593:**François Viète published Viète’s formula, an infinite product for calculating pi.**1655:**John Wallis published the Wallis product, another infinite product for approximating pi.**1660s:**Isaac Newton and Gottfried Wilhelm Leibniz developed calculus, leading to the creation of many infinite series for approximating pi.

- t = 1/4
- p = 1

**Iterate:**- a_new = (a + b) / 2
- b_new = √(a * b)
- t_new = t – p * (a – a_new)^2
- p_new = 2 * p

**Update:**- a = a_new
- b = b_new
- t = t_new
- p = p_new

- Repeat until precision is reached (123 digits)
**Calculate Pi:**Pi = (a + b)^2 / (4 * t)
