\frac{x ^{am} - x ^{n}}{x} : x^{\frac{2 am - 1}{2}} - x^{\frac{2 n - 1}{2}}

= \int x^{\frac{2 am - 1}{2}} - x^{\frac{2 n - 1}{2}} 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 x^{\frac{2 am - 1}{2}} d x - \int x^{\frac{2 n - 1}{2}} d x

\int x^{\frac{2 am - 1}{2}} d x = \frac{2 x ^{\frac{2 am + 1}{2}}}{2 am + 1}

\int x^{\frac{2 n - 1}{2}} d x = \frac{2 x ^{\frac{2 n + 1}{2}}}{2 n + 1}

= \frac{2 x ^{\frac{2 am + 1}{2}}}{2 am + 1} - \frac{2 x ^{\frac{2 n + 1}{2}}}{2 n + 1}
