Schritte zur Lösung

\int_{- 1}^{0} 4 x^{2} 4 x^{3} + 6 d x

Entferne die Konstante:

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

= 4 \cdot \int_{- 1}^{0} x^{2} 4 x^{3} + 6 d x

Wende U-Substitution an

= 4 \cdot \int_{2}^{6} \frac{u ^{2}}{6} d u

Entferne die Konstante:

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

= 4 \cdot \frac{1}{6} \cdot \int_{2}^{6} u^{2} d u

Wende die Potenzregel an

= 4 \cdot \frac{1}{6} [\frac{u ^{3}}{3}]_{2}^{6}

Vereinfache

4 \cdot \frac{1}{6} [\frac{u ^{3}}{3}]_{2}^{6} : \frac{2}{3} [\frac{u ^{3}}{3}]_{2}^{6}

= \frac{2}{3} [\frac{u ^{3}}{3}]_{2}^{6}

Berechne die Grenzen:

26 - \frac{2 2}{3}

= \frac{2}{3} (26 - \frac{2 2}{3})
