Wende U-Substitution an

= \int_{x}^{x - l n (2)} - e^{u} d u

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= - \int_{x}^{x - l n (2)} e^{u} d u

Nutze das gemeinsame Integral :

\int e^{u} d u = e^{u}

= - [e^{u}]_{x}^{x - l n (2)}

Berechne die Grenzen:

- \frac{1}{2} e^{x}

= - (- \frac{1}{2} e^{x})
