derivative of-8x-cos(x)

Lösung

\frac{d}{d x} (- 8 x - cos (x))

Lösung

- 8 + sin (x)

Schritte zur Lösung

\frac{d}{d x} (- 8 x - cos (x))

Wende die Summen-/Differenzregel an:

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

= - \frac{d}{d x} (8 x) - \frac{d}{d x} (cos (x))

\frac{d}{d x} (8 x) = 8

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

= - 8 - (- sin (x))

Vereinfache

= - 8 + sin (x)
