integral from-2 to 0 of 9x^2(2x^3+2)^2

Lösung

\int_{- 2}^{0} 9 x^{2} (2 x^{3} + 2)^{2} d x

Lösung

1376

Schritte zur Lösung

\int_{- 2}^{0} 9 x^{2} (2 x^{3} + 2)^{2} d x

Entferne die Konstante:

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

= 9 \cdot \int_{- 2}^{0} x^{2} (2 x^{3} + 2)^{2} d x

Wende U-Substitution an

= 9 \cdot \int_{- 14}^{2} \frac{u ^{2}}{6} d u

Entferne die Konstante:

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

= 9 \cdot \frac{1}{6} \cdot \int_{- 14}^{2} u^{2} d u

Wende die Potenzregel an

= 9 \cdot \frac{1}{6} [\frac{u ^{3}}{3}]_{- 14}^{2}

Vereinfache

9 \cdot \frac{1}{6} [\frac{u ^{3}}{3}]_{- 14}^{2} : \frac{3}{2} [\frac{u ^{3}}{3}]_{- 14}^{2}

= \frac{3}{2} [\frac{u ^{3}}{3}]_{- 14}^{2}

Berechne die Grenzen:

\frac{2752}{3}

= \frac{3}{2} \cdot \frac{2752}{3}

Vereinfache

= 1376
