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

= \frac{1}{2} \cdot \int_{1}^{4} 2 + \frac{1}{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

= \frac{1}{2} (\int_{1}^{4} 2 d x + \int_{1}^{4} \frac{1}{x} d x)

\int_{1}^{4} 2 d x = 6

\int_{1}^{4} \frac{1}{x} d x = 2 ln (2)

= \frac{1}{2} (6 + 2 ln (2))

Vereinfache

\frac{1}{2} (6 + 2 ln (2)) : 3 + ln (2)

= 3 + ln (2)
