Wende die partielle Integration an

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

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

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

Da die Nenner gleich sind, fasse die Brüche zusammen.:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

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