Borwein pi approximation

WebOct 15, 2024 · 1 Answer. For large n and x > 1, ( 1 + x − n) 1 + x n ≈ ( 1 + x − n) x n ≈ e, so the fixed point approximates e. For the case n = 1, a root > 1 of ( 1 + x − 1) x = x 2 / ( x + 1) will be a poor approximation for e, but will be a better approximation for the positive root of x 2 / ( x + 1) = e, which is 1 2 ( e + e 2 + 4 e) ≈ 3.5 ...

If the series is truncated at the right time, the decimal expansion of the approximation will agree with that of π for many more digits, except for isolated digits or digit groups. For example, taking five million terms yields where the underlined digits are wrong.

WebIn 1992, Jonathan Borwein and Mark Limber used the first thousand Euler numbers to calculate π to 5,263 decimal places with the Leibniz formula. [6] Euler product [ edit] The Leibniz formula can be interpreted as a Dirichlet series using the unique non-principal Dirichlet character modulo 4. In mathematics, Borwein's algorithm is an algorithm devised by Jonathan and Peter Borwein to calculate the value of 1/π. They devised several other algorithms. They published the book Pi and the AGM – A Study in Analytic Number Theory and Computational Complexity. See more These two are examples of a Ramanujan–Sato series.

The above series both give (41) as the first approximation and provide, respectively, about 6 and 8 decimal places per term. Such series exist because of the rationality of various modular invariants.
