\frac{4 - t + t ^{2}}{t ^{2}} : \frac{4}{t ^{2}} - \frac{1}{t} + 1

= \int \frac{4}{t ^{2}} - \frac{1}{t} + 1 d t

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{4}{t ^{2}} d t - \int \frac{1}{t} d t + \int 1 d t

\int \frac{4}{t ^{2}} d t = - \frac{4}{t}

\int \frac{1}{t} d t = ln ∣ t ∣

\int 1 d t = t

= - \frac{4}{t} - ln ∣ t ∣ + t
