(d^2)/(dx^2)(4xcos(x^2))

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

4 (- 6 x sin (x^{2}) - 4 x^{3} cos (x^{2}))

Solution steps

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

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

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

\frac{d}{d x} (4 (cos (x^{2}) - 2 x^{2} sin (x^{2}))) = 4 (- 6 x sin (x^{2}) - 4 x^{3} cos (x^{2}))

= 4 (- 6 x sin (x^{2}) - 4 x^{3} cos (x^{2}))

\frac{4 s}{s ^{2} + 6 s + 9}

x \to 0 lim ((1 + 3 x)^{\frac{7}{x}})

5 sin (6 t)

\int t e^{- 4 t} d t

\frac{d}{d x} (arctan (- x))
