(x,y)!(0,0) x4 4y2 x2 +2y2 First, observe that (0,0) is not in the domain of x44y2 x2+2y2. So we answer NO for Step I and move onto Step II. Notice that we can simplify this expression. We get x4 4y2 x 2+2y = (x2 2y2)(x2 +2y2) x +2y2 = x2 22y . Now we return to Step I and observe that (0,0) is in the domain of x2 2y2. Therefore, we can plug in ...

This proves the di erentiability at the origin. On the other hand, the partial derivatives are not continuous. Ideed, for x6= ywe have f x(x;y) = 2(x y)sin 1 x y cos 1 x y and f y(x;y) = 2(x ...
