Thus, what you might want to do is introduce a Bromwich contour that respects a branch cut along the part of the real axis where $\operatorname{Re}{z} \lt 1$. Apr 21 comment Using residue theorem to integrate from $-\infty$ to $\infty$ Yes, this is kosher. Check that you are correct. Apr 18 answered Can someone help me integrate this function?
