Derivative of cosx sin x and cos x

Derivative of cosx sin x and cos x The trigonometric functions \sin(x)sin(x)sine, left parenthesis, x, right parenthesis and \cos(x)cos(x)cosine, left parenthesis, x, right parenthesis play a significant role in calculus. These are their derivatives: \begin{aligned} \dfrac{d}{dx}[\sin(x)]&=\cos(x) \\\\ \dfrac{d}{dx}[\cos(x)]&=-\sin(x) \end{aligned} dx d ​ [sin(x)] dx d ​ [cos(x)] ​ =cos(x) =−sin(x) …
