derivative of e^{2x}-cos(2x)

Lösung

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

2 e^{2 x} + 2 sin (2 x)

Schritte zur Lösung

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

Wende die Summen-/Differenzregel an:

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

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

\frac{d}{d x} (e^{2 x}) = e^{2 x} \cdot 2

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

= e^{2 x} \cdot 2 - (- sin (2 x) \cdot 2)

Vereinfache
