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

Solution

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

Solution

- 4 cos (2 x)

Solution steps

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

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

= \frac{d}{d x} (- sin (2 x) \cdot 2)

\frac{d}{d x} (- sin (2 x) \cdot 2) = - 4 cos (2 x)

= - 4 cos (2 x)
