derivative of

t^{8} cos (t)

8 t^{7} cos (t) - t^{8} sin (t)

Solution steps

\frac{d}{d t} (t^{8} cos (t))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = t^{8}, g = cos (t)

= \frac{d}{d t} (t^{8}) cos (t) + \frac{d}{d t} (cos (t)) t^{8}

\frac{d}{d t} (t^{8}) = 8 t^{7}

\frac{d}{d t} (cos (t)) = - sin (t)

= 8 t^{7} cos (t) + (- sin (t)) t^{8}

Simplify

= 8 t^{7} cos (t) - t^{8} sin (t)
