comment What is the height of a regular polygon?
@user2517533, think about the triangle formed by the centres of the small circles. That gives you $\sqrt 3 r$. Then extending up and down from the appropriate centres gives an additional $2r$.

comment How to calculate $\cos(6^\circ)$?
I withdraw that comment. When I can't tell the difference between a half and a third, I should probably take it as a sign to step away from the mathematical website.

It should be sufficient that all cuts which separate the source and sink are min cuts. However, this is not necessary.

comment Mandelbrot set incorrect picture
Why do you initialise complexC and realC to $0.4$ and $0.3$ respectively? They should both be initialised to $0$.

comment Is the extended Euclidean algorithm optimal for computing modular inverses?
In CS it's standard to talk about algorithmic complexity in terms of the size of the input rather than the value it represents, so the $n$ in $O(n^2)$ would be the sum of the logarithms of the two numbers, and it's equivalent to your bound in terms of the values of the numbers.
