Linked is a proof written on the value of the Riemann Zeta function at 2 (aka the Basel Problem). My solution utilizes the Fourier transform and the strong form of L’Hopital’s rule, as well as hyperbolic trig identities, etc… While it is indeed a correct derivation, there are simpler solutions to the problem. This solution is interesting though. …i think.
