@integralsbot @infseriesbot 2- We have a brilliant solution by @arthurzqx [in thread below] via Dirichlet kernels. I am stuck, but close, using special functions, but it pays to be stubborn here. A small trick is needed for N->infinity and a transformation T->T/2 since tan(.) has half the periodicity of f. https://t.co/OLM39cCyoj — PolitiTweet.org
