Schritte zur Lösung

\int_{- 1}^{2} \frac{1}{3} x^{3} d x

Entferne die Konstante:

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

= \frac{1}{3} \cdot \int_{- 1}^{2} x^{3} d x

Wende die Potenzregel an

= \frac{1}{3} [\frac{x ^{4}}{4}]_{- 1}^{2}

Berechne die Grenzen:

\frac{15}{4}

= \frac{1}{3} \cdot \frac{15}{4}

Vereinfache

= \frac{5}{4}
