Derivative of cos square x
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 WebCalculus Derivative Calculator Step 1: Enter the function you want to find the derivative of in the editor.

WebFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. WebThe derivatives of the cosine functions, however, differ in sign: (d / d x) cos x = − sin x, (d / d x) cos x = − sin x, but (d / d x) cosh x = sinh x. ( d / d x ) cosh x = sinh x . As we continue our examination of the hyperbolic functions, we must be mindful of their similarities and differences to the standard trigonometric functions.
WebFor d/dx sin(x)cos(x), W.A. applies the product rule. For d/dx cos(x)cos(x), W.A. recognizes that we can rewrite as a composition d/dx cos^2(x) and apply the chain rule. In summary, there are some functions that can be written only as compositions, like d/dx ln(cos(x)). There are other functions that can be written only as products, like d/dx ...
