WebSolution: To find the derivative of cos2x, we will use the chain rule method. d (cos2x)/dx = d (cos2x)/d (2x) × d (2x)/dx = -sin 2x × 2 = -2 sin 2x To find the integral of cos2x, assume that 2x = u. Then 2 dx = du (or) dx = du/2. Substituting these values in the integral ∫ cos2x dx, ∫ cos2x dx = ∫ cos u (du/2) = (1/2) ∫ cos u du WebNov 14, 2024 · The formula of derivative of cos^2x is equal to the product of the sine and cosine function, that is; d/dx (cos 2 x) = - 2cos x sin x Also find the derivative of cos 3 …
