(d^2)/(dt^2)((s)(t^5-10t^2))

解答

\frac{d ^{2}}{d t ^{2}} ((s) (t^{5} - 10 t^{2}))

s (20 t^{3} - 20)

求解步骤

\frac{d ^{2}}{d t ^{2}} ((s) (t^{5} - 10 t^{2}))

\frac{d}{d t} (s (t^{5} - 10 t^{2})) = s (5 t^{4} - 20 t)

= \frac{d}{d t} (s (5 t^{4} - 20 t))

\frac{d}{d t} (s (5 t^{4} - 20 t)) = s (20 t^{3} - 20)

= s (20 t^{3} - 20)
