Use the identity sin 2x = 2 sin x cos x to find d dx -(sin 2x). Then use the identity cos 2x = cos *x - sin *x to express the derivative of sin 2x in terms of cos 2X. Find dx (sin 2x) using sin 2x = 2 sin x cos x. d dy (sin 2x) = Express the derivative of sin 2x in terms of cos 2x using cos 2x = cos ~x - sin ~x. d (sin 2x) = dxFind the derivative of the function and then evaluate at the given point y = 2x- - 4x; ( - 1,6) f'(x) = f(-1) = (Type an integer or a simplified fraction.)The function f in the figure satisfies lim f(x) = 4. Determine the maximum value of 8> 0 satisfying each statement. x-+5 107 a. If 0
