Schritte zur Lösung

\int_{0}^{1} \frac{1 + 12 t}{1 + 3 t} d t

Lange Division

\frac{1 + 12 t}{1 + 3 t} : 4 - \frac{3}{3 t + 1}

= \int_{0}^{1} 4 - \frac{3}{3 t + 1} d t

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}^{1} 4 d t - \int_{0}^{1} \frac{3}{3 t + 1} d t

\int_{0}^{1} 4 d t = 4

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

= 4 - 2 ln (2)
