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

Lösung

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

Lösung

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

Schritte zur Lösung

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

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

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

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

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