Lösung

\int \frac{( 1 + 1 - x ^{2} ) ^{2}}{1 - x ^{2}} d x

Schritte zur Lösung

\int \frac{( 1 + 1 - x ^{2} ) ^{2}}{1 - x ^{2}} d x

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

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

\int \frac{2 - x ^{2} + 1 + 1}{1 - x ^{2}} d x = 2 arcsin (x) + \frac{ln ∣ x + 1 ∣}{2} - \frac{ln ∣ x - 1 ∣}{2}

\int 1 d x = x

= 2 arcsin (x) + \frac{ln ∣ x + 1 ∣}{2} - \frac{ln ∣ x - 1 ∣}{2} + x
