6 maj 2012 · First we split $\sin^2(x)=\frac{(1-e^{2ix})+(1-e^{-2ix})}{4}$. To avoid the pole at $x=0$, drop the path of integration a bit below the real line (this function has no poles and it vanishes at infinity, so this is okay).
Write the integral as. $$I = {2}\int_ {0}^ {\infty} \frac {\sin^2 (x)} {x^2}. $$. Recalling the Mellin transform of a function $f$. $$ \int_ {0}^ {\infty} x^ {s-1} f (x)dx $$. our integral is the Mellin transform of $\sin (x)^2$ with $s=-1$. The Mellin transform is $\sin (x)^2$ given by.
