(d^2)/(dx^2)(6cos(3x+3))

解答

\frac{d ^{2}}{d x ^{2}} (6 cos (3 x + 3))

- 54 cos (3 x + 3)

求解步骤

\frac{d ^{2}}{d x ^{2}} (6 cos (3 x + 3))

\frac{d}{d x} (6 cos (3 x + 3)) = - 18 sin (3 x + 3)

= \frac{d}{d x} (- 18 sin (3 x + 3))

\frac{d}{d x} (- 18 sin (3 x + 3)) = - 54 cos (3 x + 3)

= - 54 cos (3 x + 3)
