Hi @Bob_Carpenter,
I think maybe my question is not clearly stated.
Suppose today I want to know about function A, tomorrow I want to know function B, and one day after I want to know function C (C++ algorithm or mathematical formula). Of course it is not a good idea that I create a thread every time I want to know about a new function (new to me).
I would like to know the algorithm behind a function in a way that I can do it myself every time I would do, instead of asking so many questions here.
