derivative g(t)=t^3cos(t)

Soluzione

derivata di

g (t) = t^{3} cos (t)

3 t^{2} cos (t) - t^{3} sin (t)

Fasi della soluzione

\frac{d}{d t} (t^{3} cos (t))

Applica la regola del prodotto:

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

f = t^{3}, g = cos (t)

= \frac{d}{d t} (t^{3}) cos (t) + \frac{d}{d t} (cos (t)) t^{3}

\frac{d}{d t} (t^{3}) = 3 t^{2}

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

= 3 t^{2} cos (t) + (- sin (t)) t^{3}

Semplificare

= 3 t^{2} cos (t) - t^{3} sin (t)

\frac{d}{d x} (ln (2 x^{2} - 1))
