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

Solution

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

Solution

- 8 e^{x} sin (x)

Solution steps

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

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

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

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

= - 8 e^{x} sin (x)
