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)
Semiprotected edit request on 3 July 2020Edit
This edit request has been answered. Set the answered= or ans= parameter to no to reactivate your request. 
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)
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 integralderivative definition of arc length, but you do not have to. The "Definition" subsection should be edited accordingly.
