I looked at the lectures and a couple of examples didn't really help. I know that I need to start with the search for specific points.

Which example had most in common with this problem and how was the integral in the example evaluated?

Now this example is interesting. Draw a contour with a center on the xaxis at the point z = 1 and a radius r = 1/2 and singular points: z = 0, z = +  2i, which are outside the contour. There are no special points inside the contour, so the answer is the simplest = 0.
