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

Solution

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

Solution

- 2 sin (x) - x cos (x)

Solution steps

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

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

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

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

= - 2 sin (x) - x cos (x)
