In this article, we derive, using Fourier series and multiple derivative ofthe function $\pi/\sin(\pi x)$, series representations for positive powers of$\pi$. We also show that the Euler-Wallis product can be easily obtained fromthe same formalism and deduce infinite products representations of $\pi$.

From Fourier series to infinite product representations of $\pi$ and infinite-series forms for its positive powers
