derivative of 2x-cos(x)

Lösung

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

Lösung

2 + sin (x)

Schritte zur Lösung

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

Wende die Summen-/Differenzregel an:

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

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

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

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

= 2 - (- sin (x))
