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

Solution

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

Solution

- 49 cos (7 x)

Solution steps

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

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

= \frac{d}{d x} (- sin (7 x) \cdot 7)

\frac{d}{d x} (- sin (7 x) \cdot 7) = - 49 cos (7 x)

= - 49 cos (7 x)
