derivative of x-2cos(x)

Lösung

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

Lösung

1 + 2 sin (x)

Schritte zur Lösung

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

Wende die Summen-/Differenzregel an:

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

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

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

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

= 1 - (- 2 sin (x))

Vereinfache

= 1 + 2 sin (x)
