(d^2)/(dt^2)((s)(5t^3+3t^5))

解答

\frac{d ^{2}}{d t ^{2}} ((s) (5 t^{3} + 3 t^{5}))

s (30 t + 60 t^{3})

求解步骤

\frac{d ^{2}}{d t ^{2}} ((s) (5 t^{3} + 3 t^{5}))

\frac{d}{d t} (s (5 t^{3} + 3 t^{5})) = s (15 t^{2} + 15 t^{4})

= \frac{d}{d t} (s (15 t^{2} + 15 t^{4}))

\frac{d}{d t} (s (15 t^{2} + 15 t^{4})) = s (30 t + 60 t^{3})

= s (30 t + 60 t^{3})
