(d^2)/(dx^2)((4x^2+8x)cos(x))

\frac{d ^{2}}{d x ^{2}} ((4 x^{2} + 8 x) cos (x))

- 4 x^{2} cos (x) - 16 x sin (x) - 8 x cos (x) - 16 sin (x) + 8 cos (x)

Solution steps

\frac{d ^{2}}{d x ^{2}} ((4 x^{2} + 8 x) cos (x))

\frac{d}{d x} ((4 x^{2} + 8 x) cos (x)) = cos (x) (8 x + 8) - sin (x) (4 x^{2} + 8 x)

= \frac{d}{d x} (cos (x) (8 x + 8) - sin (x) (4 x^{2} + 8 x))

\frac{d}{d x} (cos (x) (8 x + 8) - sin (x) (4 x^{2} + 8 x)) = - 4 x^{2} cos (x) - 16 x sin (x) - 8 x cos (x) - 16 sin (x) + 8 cos (x)

= - 4 x^{2} cos (x) - 16 x sin (x) - 8 x cos (x) - 16 sin (x) + 8 cos (x)

\frac{a}{s ^{2} + a ^{2}}

\frac{x ^{2}}{y ^{2} - 2} \frac{d y}{d x} = \frac{1}{2 y}

\int_{- 10}^{10} (x^{2} + x) d x

\frac{d}{d x} (x (1 - 2 x)^{3})

f (x) = 8 x - 3 x^{2}
