(d^2)/(dx^2)(cos(5x))

Solution

\frac{d ^{2}}{d x ^{2}} (cos (5 x))

Solution

- 25 cos (5 x)

Solution steps

\frac{d ^{2}}{d x ^{2}} (cos (5 x))

\frac{d}{d x} (cos (5 x)) = - sin (5 x) \cdot 5

= \frac{d}{d x} (- sin (5 x) \cdot 5)

\frac{d}{d x} (- sin (5 x) \cdot 5) = - 25 cos (5 x)

= - 25 cos (5 x)
