82. Infinite Expressions For Pi william brouncker (ca. 1660 s) rewrote Wallis formula as a continued fraction,which Wallis and later Euler (1775) proved to be equivalent. http://www.geom.uiuc.edu/~huberty/math5337/groupe/expresspi.html

Infinite Expressions for Pi This page lists a number of infinite expressions of . Proofs are not provided here, but the viewer is encouraged to study the sources listed in the reference page John Wallis (1655) took what can now be expressed as and without using the binomial theorem or integration (not invented yet) painstakingly came up with a formula for to be William Brouncker (ca. 1660's) rewrote Wallis' formula as a continued fraction, which Wallis and later Euler (1775) proved to be equivalent. It is unknown how Brouncker himself came up with the continued fraction, and the fact that arctan(1) = /4 to obtain the series Unfortunately, this series converges to slowly to be useful, as it takes over 300 terms to obtain a 2 decimal place precision. To obtain 100 decimal places of , one would need to use at least 10^50 terms of this expansion! History books credit Sir Isaac Newton (ca. 1730's) with using the series expansion of the arcsine function, and the fact that arctan(1/2) = /6 to obtain the series This arcsine series converges much faster than using the arctangent. (Actually, Newton used a slightly different expansion in his original text.) This expansion only needed 22 terms to obtain 16 decimal places for
