\frac{d}{d x} (1 - 5 cos (x))

5 sin (x)

Solution steps

\frac{d}{d x} (1 - 5 cos (x))

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (1) - \frac{d}{d x} (5 cos (x))

\frac{d}{d x} (1) = 0

\frac{d}{d x} (5 cos (x)) = - 5 sin (x)

= 0 - (- 5 sin (x))

Simplify

= 5 sin (x)
