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

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

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

Vereinfache

= [x arcsin (x) + 1 - x^{2}]_{\frac{1}{4}}^{1}

Berechne die Grenzen:

\frac{π}{2} - \frac{arcsin ( \frac{1}{4} ) + 15}{4}

= \frac{π}{2} - \frac{arcsin ( \frac{1}{4} ) + 15}{4}
