comment Show that $\int_{C} \frac{e^{az}}{\sin(\pi z)} \,dz \rightarrow 0 \quad as \quad R \rightarrow \infty$
Since $|e^{az}| = e^{\text{Re}(a) \, \text{Re}(z)} e^{- \text{Im}(a) \text{Im}(z)}$ and $\left| \sin (\pi z) \right| \sim \frac{1}{2} e^{\pi \text{Im}(z)}$ as $\text{Im}(z) \to + \infty$, it looks like the integral should vanish if $\text{Im} (a) > -\pi$.
