derivative f(x)=2cos(x)+cos^2(x)

Lösung

ableitung von

f (x) = 2 cos (x) + cos^{2} (x)

Lösung

- 2 sin (x) - sin (2 x)

Schritte zur Lösung

\frac{d}{d x} (2 cos (x) + cos^{2} (x))

Wende die Summen-/Differenzregel an:

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

= \frac{d}{d x} (2 cos (x)) + \frac{d}{d x} (cos^{2} (x))

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

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

= - 2 sin (x) - sin (2 x)
