\frac{5 x ^{3} - 4 x}{1 - x ^{4}} : \frac{5 x ^{3}}{1 - x ^{4}} - \frac{4 x}{1 - x ^{4}}

= \int \frac{5 x ^{3}}{1 - x ^{4}} - \frac{4 x}{1 - x ^{4}} 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{5 x ^{3}}{1 - x ^{4}} d x - \int \frac{4 x}{1 - x ^{4}} d x

\int \frac{5 x ^{3}}{1 - x ^{4}} d x = - \frac{5}{2} 1 - x^{4}

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

= - \frac{5}{2} 1 - x^{4} - 2 arcsin (x^{2})
