## Complex Integration

Given a line L that goes from $l-\infty i$ to $l+\infty i$ and a line C that goes from $c+\infty i$ to $c-\infty i$, $l \neq c, \; l,c > 0$, and a function $f(z)$ such that $f(z)$ is analytic everywhere in the strip aside from one pole inside the strip. Call the residue at that point $S$.

Is it true that $\int_{L} f(s)ds + \int_{C} f(s)ds = 2\pi i S$ ?
