Multipliziere aus

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

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

\int \frac{1}{4 - x ^{2}} d x = arcsin (\frac{1}{2} x)

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

= arcsin (\frac{1}{2} x) - 4 - x^{2}

Füge eine Konstante zur Lösung hinzu
