Hint refers to this problem:
2. Let ry when the right side is defined, and let f (0,0 0. Prove that its partial derivatives exist at the origin (note that I did this part in class), but that it is not differentiable at the origin according to the definition in problem 1. (Hint: You have to cite the conclusion of problem 1. You also need to set up a 2-dimensional limit which can be handled in various ways.)
