comment Quadratic Bezier curves representation as implicit quadratic equation
You have an infinite supply of points satisfying $F(P) = 0$. What can you get with that?

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.

comment Determine whether a graph has a unique max flow
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 $0$.

@simpleton, indeed. But can you show that that's the correct answer?

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.

comment If a sequence of natural numbers satisfies $\gcd(a_{i+1},a_{i})>a_{i-1}$, then $a_{n}>2^n$
$\mathbb{N}$ is ambiguous as to whether it includes $0$ or not, which is relevant.
