Best ResponseYou've already chosen the best response.0d/dx > 3e^(3x+4y)cos(5z) d/dy > 4e^(3x+4y)cos(5z) d/dz > 5e^(3x+4y)sin(5z)

Best ResponseYou've already chosen the best response.0z is the easiest. hold everything else constant and the derivative of \[cos(5z)=5sin(5z)\] so answer is just \[5e^{3x+4y}sin(5z)\]

Best ResponseYou've already chosen the best response.0f (x, y, z) = e ^ (3x +4 y) cos 5z with respect to x d/dx > 3e^(3x+4y)cos(5z) then the other variables do not behave as constants?
