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.1You have to check the last answer very carefully. You are doing this right, but you are making mistakes. Check them.

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.
