Best ResponseYou've already chosen the best response.0f'w = w X (1)(w^2+z^2)^2 X 2w + (w^2+z^2)^1 (1) = 2w^3 (w^2+z^2) + (w^2+z^2)^1

Best ResponseYou've already chosen the best response.1f'w = w X (1)(w^2+z^2)^2 X 2w + (w^2+z^2)^1  This is OK, but this = 2w^3 (w^2+z^2) + (w^2+z^2)^1 is not. Try to find the common denominator in the first one and subtract the fractions.
