(d^2)/(dx^2)(7cos(3x))

Solution

\frac{d ^{2}}{d x ^{2}} (7 cos (3 x))

Solution

- 63 cos (3 x)

Solution steps

\frac{d ^{2}}{d x ^{2}} (7 cos (3 x))

\frac{d}{d x} (7 cos (3 x)) = - 21 sin (3 x)

= \frac{d}{d x} (- 21 sin (3 x))

\frac{d}{d x} (- 21 sin (3 x)) = - 63 cos (3 x)

= - 63 cos (3 x)
