\frac{8 + x}{1 + x ^{2}} : \frac{8}{1 + x ^{2}} + \frac{x}{1 + x ^{2}}

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} \frac{8}{1 + x ^{2}} d x + \int_{0}^{1} \frac{x}{1 + x ^{2}} d x

\int_{0}^{1} \frac{8}{1 + x ^{2}} d x = 2 π

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

= 2 π + \frac{1}{2} ln (2)
