Q: Is it always possible to go from one identity to another?

user3002473This question was inspired by this Quora question. I'm sure lots of you are familiar with the fact that we have many different representations of $\pi$, things like $$ \begin{align} \pi & = \sqrt{6\zeta(2)} \\ & = \frac{4}{1 + \frac{1^2}{3 + \frac{2^2}{5 + \frac{3^2}{7 + \frac{4^2}{9 + \ddots}}}...

Just this evening I had to remove the twice. The second time was almost exclusively old questions. I wish we had a 20k rep limit on new tags.
