(d^2)/(dx^2)(sin(bx)-2cos(bx))

解

\frac{d ^{2}}{d x ^{2}} (sin (b x) - 2 cos (b x))

解

- b^{2} sin (b x) + 2 b^{2} cos (b x)

解答ステップ

\frac{d ^{2}}{d x ^{2}} (sin (b x) - 2 cos (b x))

\frac{d}{d x} (sin (b x) - 2 cos (b x)) = b cos (b x) + 2 b sin (b x)

= \frac{d}{d x} (b cos (b x) + 2 b sin (b x))

\frac{d}{d x} (b cos (b x) + 2 b sin (b x)) = - b^{2} sin (b x) + 2 b^{2} cos (b x)

= - b^{2} sin (b x) + 2 b^{2} cos (b x)
