Thanks for using our derivative … Derivative Of sin^2x, sin^2(2x) – The differentiation of trigonometric functions is the mathematical process of finding the derivative of a trigonometric function, or its rate of change with respect to a variable. Common trigonometric functions include sin(x), cos(x) and tan(x). For example, the derivative of f(x) = sin(x) is represented as f ′(a) = cos(a). f ′(a) is the rate of change Basic and Pythagorean Identities. csc⁡(x)=1sin⁡(x)\csc(x) = \dfrac{1}{\sin(x)}csc(x)=sin(x)1​ … We have [math]y=[/math][math]cos(x+y)[/math] Differentiating, [math]\dfrac{dy}{dx} = -\sin(x+y)(x+y)'[/math] [Chain rule] [math]\Rightarrow \dfrac{dy}{dx} = -\sin(x+y Let u = sin2x; v =cos2xOn differentiating w.r.t x respectively, we getdxdu =2sinxcosx= sin2xdxdv =−2cosxsinx= −sin2xNow, dvdu = dv/dxdu/dx = −sin2xsin2x = −1. Answer verified by Toppr. Sin 2x cos 2x = ½ (2 sin 2x cos 2x) (Or) ½ sin 4x By differentiating the given function: d/dx [ ½ sin 4x ] = ½ [d/dx (sin 4x)] = ½ [cos 4x d/dx(4x) ] = ½ [cos (4x) (4) ] Therefore, the derivative of sin 2x cos 2x is d/dx (Sin 2x Cos 2x) = 2 Cos (4x) Solved Examples.

The process of finding this derivative uses the chain rule .
