integral of x^2-1/x

Lösung

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

Lösung

\frac{x ^{3}}{3} - ln ∣ x ∣ + C

Schritte zur Lösung

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

\int x^{2} d x = \frac{x ^{3}}{3}

\int \frac{1}{x} d x = ln ∣ x ∣

= \frac{x ^{3}}{3} - ln ∣ x ∣

Füge eine Konstante zur Lösung hinzu

= \frac{x ^{3}}{3} - ln ∣ x ∣ + C
