On the flint hill series

In this note we study the flint hill series of the form begin{align} sum limits_{n=1}^{infty}frac{1}{(sin^2n) n^3} onumber end{align}via a certain method. The method works essentially by erecting certain pillars sufficiently close to the terms in the series and evaluating the series at those spots. This allows us to relate the convergence and the divergence of the series to other series that are somewhat tractable. In particular we show that the convergence of the flint hill series relies very heavily on the condition that for any small $epsilon>0$ begin{align} bigg|sum limits_{i=0}^{frac{n+1}{2}}sum limits_{j=0}^{i}(-1)^{i-j}binom{n}{2i+1} binom{i}{j}bigg|^{2s} leq |(sin^2n)|n^{2s+2-epsilon} onumber end{align}for some $sin mathbb{N}$.
