    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?
