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

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

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

Solution steps

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

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

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

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

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