integral of (x^2+1)x

Lösung

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

Lösung

\frac{x ^{4}}{4} + \frac{x ^{2}}{2} + C

Schritte zur Lösung

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

Multipliziere aus

(x^{2} + 1) x : x^{3} + x

= \int x^{3} + 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^{3} d x + \int x d x

\int x^{3} d x = \frac{x ^{4}}{4}

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

= \frac{x ^{4}}{4} + \frac{x ^{2}}{2}

Füge eine Konstante zur Lösung hinzu

= \frac{x ^{4}}{4} + \frac{x ^{2}}{2} + C
