# Math Help - Complex Question

1. ## Complex Question

I am confused on how to integrate this. This problem is asking me to find the integral using the definition of the integral is complex analysis. The function is

$\int_C \sin z dz$ where $C$ is the contour from $-2i$ to $1-2i$. I don't see how to do this at all. How do I rewrite this in order to do this problem? There is probably a simple way to do this one, but I am not seeing it right now for some reason. Thanks in advance for an idea of where to go with this.

Like $e^{z}$, also $\sin z$ is analytic $\forall z \in \mathbb{C}$, so that ...

Kind regards
