Derivative of cos square x
WebDec 22, 2024 · Trigonometric Function Derivatives. As was said, the derivative of cos(x) is one that is well known.Though it's always useful to know how to find a derivative, knowing some key derivatives by ... 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
