WebPython library for arbitrary-precision floating-point arithmetic - mpmath/identification.py at master · mpmath/mpmath In mathematics, Machin-like formulae are a popular technique for computing π (the ratio of the circumference to the diameter of a circle) to a large number of digits. They are generalizations of John Machin's formula from 1706: $${\displaystyle {\frac {\pi }{4}}=4\arctan {\frac {1}{5}}-\arctan {\frac {1}{239}}}$$which … Meer weergeven The angle addition formula for arctangent asserts that if An insightful way to visualize equation 3 is to picture … Meer weergeven One of the most important parameters that characterize computational efficiency of a Machin-like formula is the Lehmer's measure, defined as $${\displaystyle {\it {\lambda }}=\sum _{n=1}^{N}{\frac {1}{\log _{10}(b_{n}/a_{n})}}}$$ In order to obtain the Lehmer's measure as small as … Meer weergeven The 2002 record for digits of π, 1,241,100,000,000, was obtained by Yasumasa Kanada of Tokyo University. The … Meer weergeven For large computations of $${\displaystyle \pi }$$, the binary splitting algorithm can be used to compute the arctangents much, much more quickly than by adding the terms in the Taylor series naively one at a time. In practical implementations such as y-cruncher, … Meer weergeven In the special case where the numerator $${\displaystyle a_{n}=1}$$, there are exactly four solutions having only two terms. All four were found by John Machin in 1705–1706, but only one of them became widely known when it was published in Meer weergeven There are further methods to derive Machin-like formulas for $${\displaystyle \pi }$$ with reciprocals of integers. One is given by the following formula: where Meer weergeven • Weisstein, Eric W. "Machin-like formulas". MathWorld. • The constant π • Machin's Merit at MathPages Meer weergeven

http://educ.jmu.edu/%7Elucassk/Seminars/Pi%20Formulas.pdf WebWe could try to generate a custom Machin-like formula by running the PSLQ algorithm with a few inverse cotangent values, for example acot(2), acot(3) … acot(10). Unfortunately, there is a linear dependence among these values, resulting in only that dependence being detected, with a zero coefficient for \(\pi\): how do you pass a swab drug test

I can only suggest that the FFT algorithm for the Chudnovsky formula requires relatively smaller algebraic manipulations to compute digits of $\pi$. Perhaps the FFT algorithm for the Machin like formulas has ...
