= [x arccos (8 x) - \int - \frac{8 x}{1 - 64 x ^{2}} d x]_{0}^{\frac{1}{8}}

\int - \frac{8 x}{1 - 64 x ^{2}} d x = \frac{1}{8} 1 - 64 x^{2}

= [x arccos (8 x) - \frac{1}{8} 1 - 64 x^{2}]_{0}^{\frac{1}{8}}

Vereinfache

[x arccos (8 x) - \frac{1}{8} 1 - 64 x^{2}]_{0}^{\frac{1}{8}} : [\frac{1}{8} (8 x arccos (8 x) - 1 - 64 x^{2})]_{0}^{\frac{1}{8}}

= [\frac{1}{8} (8 x arccos (8 x) - 1 - 64 x^{2})]_{0}^{\frac{1}{8}}
