Lösung

ln (3) + 2

+1

Dezimale

Schritte zur Lösung

\int_{0}^{2} \frac{x + 2}{x + 1} d x

\frac{x + 2}{x + 1} = \frac{1}{x + 1} + 1

= \int_{0}^{2} \frac{1}{x + 1} + 1 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

= \int_{0}^{2} \frac{1}{x + 1} d x + \int_{0}^{2} 1 d x

\int_{0}^{2} \frac{1}{x + 1} d x = ln (3)

\int_{0}^{2} 1 d x = 2

= ln (3) + 2
