The derivative of the cosine of a function is equal to minus the sine of the function times the derivative of the function, in other words, if $f(x) = \cos(x)$, then $f'(x) = -\sin(x)\cdot D_x(x)$

$-\frac{d}{dy}\left(2y\right)\sin\left(2y\right)$
Learn how to solve basic differentiation rules problems step by step online. Find the derivative of cos(2y). The derivative of the cosine of a function is equal to minus the sine of the function times the derivative of the function, in other words, if f(x) = \cos(x), then f'(x) = -\sin(x)\cdot D_x(x). The derivative of a function multiplied by a constant (2) is equal to the constant times the derivative of the function. The derivative of the linear function is equal to 1.
