= [\frac{1}{2} t^{2} arcsec (t) - \int \frac{t ^{2}}{2 t ^{2} t ^{2} - 1} d t]_{\frac{2}{3}}^{2}

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

= [\frac{1}{2} t^{2} arcsec (t) - \frac{1}{2} t^{2} - 1]_{\frac{2}{3}}^{2}

Vereinfache

[\frac{1}{2} t^{2} arcsec (t) - \frac{1}{2} t^{2} - 1]_{\frac{2}{3}}^{2} : [\frac{1}{2} (t^{2} arcsec (t) - t^{2} - 1)]_{\frac{2}{3}}^{2}

= [\frac{1}{2} (t^{2} arcsec (t) - t^{2} - 1)]_{\frac{2}{3}}^{2}
