integral from 1 to e^2 of ((In(x))^2)/x

Lösung

\int_{1}^{e^{2}} \frac{( I n ( x ) ) ^{2}}{x} d x

\frac{( e ^{4} - 1 ) I ^{2} n ^{2}}{2}

Schritte zur Lösung

\int_{1}^{e^{2}} \frac{( I n x ) ^{2}}{x} d x

Vereinfache

\frac{( I n x ) ^{2}}{x} : I^{2} n^{2} x

= \int_{1}^{e^{2}} I^{2} n^{2} x d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= I^{2} n^{2} \cdot \int_{1}^{e^{2}} x d x

Wende die Potenzregel an

= I^{2} n^{2} [\frac{x ^{2}}{2}]_{1}^{e^{2}}

Berechne die Grenzen:

\frac{e ^{4}}{2} - \frac{1}{2}

= I^{2} n^{2} (\frac{e ^{4}}{2} - \frac{1}{2})
