Coprime approximation to piEdit

There is an insane method of estimating pi given by one R. Chartres in Philosophical Magazine from 1840 based on the probability of coprimality. SpinningSpark 08:24, 20 May 2020 (UTC)

Lets change DOI on Salikhov, V. (2008). "On the Irrationality Measure of pi"Edit

to 10.1134/S0001434610090294 because SciHub only gives correct article on THAT DOI. 2A00:1FA0:44DF:31F8:C1A6:49C:82FC:FAA8 (talk) 16:53, 1 July 2020 (UTC)

Semi-protected edit request on 3 July 2020Edit

Please add the missing word (in bold):
The invention of calculus soon led to the calculation of hundreds of digits of π, enough for all practical scientific computations. 95.49.71.94 (talk) 16:25, 3 July 2020 (UTC)

  Done, thanks! ‑‑ElHef (Meep?) 16:49, 3 July 2020 (UTC)

Defining π with circumference without integral calculusEdit

In his book, Remmert referred to integral definitions, not to the circumference definition. Not all definitions of π with circumference rely on integral calculus. You can use polygonal paths and then define arc length as a limit of a sum of certain lengths of line segments. This does not make use of derivatives and integrals. You can then prove that this definition is equivalent to the integral-derivative definition of arc length, but you do not have to. The "Definition" subsection should be edited accordingly.
