derivative of-2cos(x-x)

Lösung

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

Lösung

2 sin (x) - 1

Schritte zur Lösung

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

Wende die Summen-/Differenzregel an:

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

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

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

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

= - (- 2 sin (x)) - 1

Vereinfache

= 2 sin (x) - 1
