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

Lösung

ableitung von

f (x) = cos (2 x) + sin (2 x)

Lösung

- sin (2 x) \cdot 2 + cos (2 x) \cdot 2

Schritte zur Lösung

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

Wende die Summen-/Differenzregel an:

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

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

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

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

= - sin (2 x) \cdot 2 + cos (2 x) \cdot 2
