Consider the function given as example in lecture: f(x, y) = (e x cos(y), ex sin(y)) (6.2) Denote a = (0, π/3) and b = f(a). Let f −1 be a continuous inverse of f defined in a neighborhood of b. Find an explicit formula for f −1 and compute Df−1 (b). Compare this with the derivative formula given by the Inverse Function Theorem.
