integral ln((e^x)/(x^2))

Lösung

integral

ln (\frac{e ^{x}}{x ^{2}})

Lösung

\frac{x ^{2}}{2} - 2 x ln (x) + 2 x + C

Schritte zur Lösung

\int ln (\frac{e ^{x}}{x ^{2}}) d x

Vereinfache

ln (\frac{e ^{x}}{x ^{2}}) : x - ln (x^{2})

= \int x - ln (x^{2}) d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int x d x - \int ln (x^{2}) d x

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

\int ln (x^{2}) d x = 2 x ln (x) - 2 x

= \frac{x ^{2}}{2} - (2 x ln (x) - 2 x)

Vereinfache

= \frac{x ^{2}}{2} - 2 x ln (x) + 2 x

Füge eine Konstante zur Lösung hinzu

= \frac{x ^{2}}{2} - 2 x ln (x) + 2 x + C
