1. The problem statement, all variables and given/known data Suppose f : ℝ→ℝ and g : ℝ →ℝ are continuous. Suppose that f is odd and g is even. Define h(x,y) : f(x)*g(y). Let D be a disk centered at the origin in the plane. What is ∫∫h(x,y)dA? D 3. The attempt at a solution I know there's probably a trick to it. Is it 0 because h becomes odd over a disk that is symmetrical to the origin?
