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

$\displaystyle \int_C \sin z dz$ where $\displaystyle C$ is the contour from $\displaystyle -2i$ to $\displaystyle 1-2i$. 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.
