Problem 3 0 points possible (ungraded, results hidden) Let f (z) =- 9 Part (a) Integrate the function f (z)along the curve C in the complex plane given by a = _from x = 0.5 to x = 2 Part (b) Integrate the same function along the unit circle in the complex plane, i.e. on /z| = 1. Problem 4 0 points possible (ungraded, results hidden) Let f (z) = e? Part (a) Find the integral of the function f ( z )on the circle of radius 7 centered around 0 in the complex plane. Part (b) Now, find the integral of the same function on an eclipse in the complex plane given by the equation " + 0 = 1
