Unformatted text preview: a + cos = 2 a 2-1 . [ Hint: You can realize this integral as the parametrized form of an integral over the unit circle by setting z = e i .] Exercise 3. Suppose that f is analytic on a disk D and that is a simple closed curve in D . Suppose that f is constant on . Prove that f takes on the same constant value everywhere inside as well....
