1
Simplifying
$\frac{d}{dx}\left(\cos\left(x\right)\right)$
2
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 $f'(x) = -\sin(x)\cdot D_x(x)$
$-\sin\left(x\right)$
Final answer to the problem
