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

= \int_{- 3}^{- 2} \frac{1}{u} + \frac{3}{u ^{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_{- 3}^{- 2} \frac{1}{u} d u + \int_{- 3}^{- 2} \frac{3}{u ^{2}} d u

\int_{- 3}^{- 2} \frac{1}{u} d u = ln (2) - ln (3)

\int_{- 3}^{- 2} \frac{3}{u ^{2}} d u = \frac{1}{2}

= ln (2) - ln (3) + \frac{1}{2}
