Wende die partielle Integration an

= [\frac{2}{3} t^{\frac{3}{2}} ln (t) - \int \frac{2}{3} t^{\frac{1}{2}} d t]_{1}^{7}

\int \frac{2}{3} t^{\frac{1}{2}} d t = \frac{4}{9} t^{\frac{3}{2}}

= [\frac{2}{3} t^{\frac{3}{2}} ln (t) - \frac{4}{9} t^{\frac{3}{2}}]_{1}^{7}

Berechne die Grenzen:

\frac{14 7}{3} ln (7) - \frac{28 7}{9} + \frac{4}{9}

= \frac{14 7}{3} ln (7) - \frac{28 7}{9} + \frac{4}{9}
