Detail solution

Let $u = 5$ .
The derivative of cosine is negative sine:

$\frac{d}{d u} \cos{\left(u \right)} = - \sin{\left(u \right)}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} 5$ :
1. The derivative of the constant $5$ is zero.
The result of the chain rule is:

$0$

The answer is:
