I was parametrizing that piece as z = x & dz=dx and evaluating the integral between 1 and 5. I guess I am stuck on how to actually incorporate the given path into an integral.
From plotting the given path I know that the path is a curve that extends from z = 1 to z=5 on the complex plane. My plan was to parametrize the distance from z = 1 to 5 as z = x, and create a closed contour that encloses z=0, where I could use Cauchy's Integral Formula, with f(z) being 1 / (z +...
