Problem 6. Use Laplace transform to solve the following differential equation:
(a) Assume that Re{f(z)} = x3 -3xy2. Find the imaginary part Im{f(z)} so that f(z) is analytic for all x .
(b) Assume that u(x, y) = x3 +3xy2. Show that it is impossible to find a real-valued function v(x, y) such that f(z) = u(x,y) + iu(x,y) is differentiable with respect to z for all z .
(b) Find the Taylor series expansion of f(z) about the point z = 0; that is, find the coefficients such that
in a certain neighborhood of x = 0.
