\int_{1}^{6} \frac{x ^{2} + 1}{7 x - x ^{2}} d x

\frac{x ^{2} + 1}{7 x - x ^{2}} = \frac{7 x + 1}{7 x - x ^{2}} - 1

= \int_{1}^{6} \frac{7 x + 1}{7 x - x ^{2}} - 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_{1}^{6} \frac{7 x + 1}{7 x - x ^{2}} d x - \int_{1}^{6} 1 d x

\int_{1}^{6} \frac{7 x + 1}{7 x - x ^{2}} d x = 7 ln (6) + \frac{2 ln ( 6 )}{7}

\int_{1}^{6} 1 d x = 5

= 7 ln (6) + \frac{2 ln ( 6 )}{7} - 5
