History

  • In 1706, another mathematician named John Machin developed a refinement on Gregory's formula, yielding the formula still used today by computer programmers to compute pi:

  • A British mathematician William Jones in 1706, who wrote pi- 3.14159
  • In 1761 Lambert proved that Pi is a irrational number.
  • In 1882 Lindeman proved that Pi can not be the root of any algerbraic equation. Ancient Egyptians calculated the area of a circle by the following formula (where d is the diameter of the circle):
  • Using this formula, an Englishman named William Shanks calculated pi to 707 places, a labor of many years, which he published in 1873
  • This symbol was adopted by Euler in 1737 and became the standard symbol for pi.
