I was looking at the Dirichlet integral
12π∫π−π(sin((N+12)x))sin(x2)dx
and it seems to be possible to integrate using complex analysis. I attempted this using the residue theorem but my understanding of complex analysis is still quite shallow and I was unable to derive an answer. Is there any way to do this integral with complex analysis?
