Schritte zur Lösung

\int_{1}^{3} arctan (\frac{1}{x}) d x

Wende die partielle Integration an

= [x arctan (\frac{1}{x}) - \int - \frac{x}{1 + x ^{2}} d x]_{1}^{3}

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

= [x arctan (\frac{1}{x}) - (- \frac{1}{2} ln 1 + x^{2})]_{1}^{3}

Vereinfache

[x arctan (\frac{1}{x}) - (- \frac{1}{2} ln 1 + x^{2})]_{1}^{3} : [\frac{1}{2} (2 x arctan (\frac{1}{x}) + ln 1 + x^{2})]_{1}^{3}

= [\frac{1}{2} (2 x arctan (\frac{1}{x}) + ln 1 + x^{2})]_{1}^{3}

Berechne die Grenzen:

\frac{2 3 ln ( 2 ) + 2 π - 3 π}{4 3}

= \frac{2 3 ln ( 2 ) + 2 π - 3 π}{4 3}
