integral of (13)/(x^2+1)

Lösung

\int \frac{13}{x ^{2} + 1} d x

Lösung

13 arctan (x) + C

Schritte zur Lösung

\int \frac{13}{x ^{2} + 1} d x

Entferne die Konstante:

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

= 13 \cdot \int \frac{1}{x ^{2} + 1} d x

Nutze das gemeinsame Integral :

\int \frac{1}{x ^{2} + 1} d x = arctan (x)

= 13 arctan (x)

Füge eine Konstante zur Lösung hinzu

= 13 arctan (x) + C
