Lösung

\int_{0}^{l n (3)} 2 (3 - x e^{x}) d x

Lösung

4

Schritte zur Lösung

\int_{0}^{l n (3)} 2 (3 - x e^{x}) d x

Entferne die Konstante:

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

= 2 \cdot \int_{0}^{l n (3)} 3 - x e^{x} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 2 (\int_{0}^{l n (3)} 3 d x - \int_{0}^{l n (3)} x e^{x} d x)

\int_{0}^{l n (3)} 3 d x = 3 ln (3)

\int_{0}^{l n (3)} x e^{x} d x = 3 ln (3) - 2

= 2 (3 ln (3) - (3 ln (3) - 2))
