derivative of cos(2x-1)

Lösung

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

Lösung

- 2 sin (2 x)

Schritte zur Lösung

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

Wende die Summen-/Differenzregel an:

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

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

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

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

= - sin (2 x) \cdot 2 - 0

Vereinfache

= - 2 sin (2 x)
