    Trying to differentiate using function of a function/Chain rule

    Homework Statement Using the function of a function formula differentiate the following: y = (cos 2x)3 Homework Equations dy/dx = dy/du * du/dx The Attempt at a Solution y = (cos 2x)3 u = cos 2x y = u3 dy/du = -2sin2x du/dy = 3u2 dy/dx = dy/du * du/dx dy/dx =...
