Convergence of $\sum(n^3\sin^2n)^{-1}$

There is an even bigger reduction that can be done: Theorem: The Flint Hills series converges if and only if the series $$ \sum_{n = 1}^\infty \frac{1}{q_n^3 (q_n\pi - p_n)^2} \qquad{(1)} $$ converge …

Signed variant of the Flint Hills series

You mentioned my argument from the other thread, which can be used to show that if $\mu(\pi) < 3$, then your series converges. But this also means you can't get any further information about $\mu(\pi) …
