comment Prove $\int_{0}^{\pi}\frac{x^2}{\sqrt{5}-2\cos{x}}dx=\frac{\pi^3}{15}+2\pi\ln^2{\left(\frac{1+\sqrt{5}}{2}\right)}$ without contour integration
FWIW The integral has a singularity at $x=i\log\frac{1+\sqrt{5}}{2}$ so it's just a matter of finding the right contour...

comment A lemma on the growth of the number of certain edge paths for a given train track
If anyone wanted to search MO for this question using the words in the lemma they'd be thwarted by the use of an image instead of text.

It's in the software engineering textbooks.

comment Where does the word “torsion” in algebra come from?
@Kundor Yeah that's roughly the picture I had but then it struck me that nobody had ever explicitly said that to me.

comment Show that a 2nd derivative is zero given that an interior point attains the same value as the boundary points
By and large, everything mathematicians do is proving theorems. You might do better with a more informative title so people can tell if this question is in their specific domain of knowledge.

Are you able to expand on the sense of "twisted" that is meant here? I did some algebraic topology but I'm not sure what kind of twisting is picked out by an element of finite order in a homology group.
