\frac{1 + u ^{2}}{u} : \frac{1}{u} + u^{\frac{3}{2}}

= \int \frac{1}{u} + u^{\frac{3}{2}} d u

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{1}{u} d u + \int u^{\frac{3}{2}} d u

\int \frac{1}{u} d u = 2 u

\int u^{\frac{3}{2}} d u = \frac{2}{5} u^{\frac{5}{2}}

= 2 u + \frac{2}{5} u^{\frac{5}{2}}

Setze in

u = tan (x)

ein

= 2 tan (x) + \frac{2}{5} tan^{\frac{5}{2}} (x)
