(d^2)/(dx^2)(3e^xcos(x))

Lösung

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

Lösung

- 6 e^{x} sin (x)

Schritte zur Lösung

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

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

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

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

= - 6 e^{x} sin (x)
