1. The problem statement, all variables and given/known data Evaluate the following line integrals in the complex plane by direct integration. 2. Relevant equations Z= x+i y = Cos(θ) +i Sin(θ) = e^i*θ 3. The attempt at a solution I'm not sure how to evaluated this by hand. I tried using Z= x+i y = Cos(θ) +i Sin(θ), and evaluating the integral at dθ. However, I'm not sure how to change the bounds. It seems to me that point A starts at 2pi, and then point B is at 2pi + i *(infinity). what exactly does that mean?
