derivative of-x+2cos(2x)

Lösung

\frac{d}{d x} (- x + 2 cos (2 x))

Lösung

- 1 - 4 sin (2 x)

Schritte zur Lösung

\frac{d}{d x} (- x + 2 cos (2 x))

Wende die Summen-/Differenzregel an:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d x}{d x} = 1

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

= - 1 - 4 sin (2 x)
