(d^2)/(dx^2)(3x^2cos(8x))

Lösung

\frac{d ^{2}}{d x ^{2}} (3 x^{2} cos (8 x))

Lösung

3 (2 cos (8 x) - 32 x sin (8 x) - 64 x^{2} cos (8 x))

Schritte zur Lösung

\frac{d ^{2}}{d x ^{2}} (3 x^{2} cos (8 x))

\frac{d}{d x} (3 x^{2} cos (8 x)) = 3 (2 x cos (8 x) - 8 x^{2} sin (8 x))

= \frac{d}{d x} (3 (2 x cos (8 x) - 8 x^{2} sin (8 x)))

\frac{d}{d x} (3 (2 x cos (8 x) - 8 x^{2} sin (8 x))) = 3 (2 cos (8 x) - 32 x sin (8 x) - 64 x^{2} cos (8 x))

= 3 (2 cos (8 x) - 32 x sin (8 x) - 64 x^{2} cos (8 x))
