Pi Approximation Day (2023)

[Gerson W. Barbosa]

Today is Pi Approximation Day, at least in countries which use DD/MM date format.

No new outstanding pi approximations, just a minor improvement

on one of Ramanujan's:

\(\sqrt[4]{\frac{2143+\left({6+\sqrt{6-\frac{6}{6^6}}}\right)^{-6}}{22}}\)

on one of mine:

\(\frac{\ln\left({\frac{16\times\ln\left({878}\right)}{\ln\left({16\ln\left({878​}\right)}\right)}}\right)}{1+\left({\frac{5}{94+\sqrt{2}}}\right)^8}\)


Happy Pi Approximation Day!
