\frac{d}{d x} (x sinh (x) - 8 cosh (x))

x cosh (x) - 7 sinh (x)

Solution steps

\frac{d}{d x} (x sinh (x) - 8 cosh (x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (x sinh (x)) - \frac{d}{d x} (8 cosh (x))

\frac{d}{d x} (x sinh (x)) = sinh (x) + x cosh (x)

\frac{d}{d x} (8 cosh (x)) = 8 sinh (x)

= sinh (x) + x cosh (x) - 8 sinh (x)

Simplify

= x cosh (x) - 7 sinh (x)
