derivative of 1-2cos(x)

Lösung

\frac{d}{d x} (1 - 2 cos (x))

2 sin (x)

Schritte zur Lösung

\frac{d}{d x} (1 - 2 cos (x))

Wende die Summen-/Differenzregel an:

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

= \frac{d}{d x} (1) - \frac{d}{d x} (2 cos (x))

\frac{d}{d x} (1) = 0

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

= 0 - (- 2 sin (x))
