Schritte zur Lösung

\int_{- 3}^{- 1} x^{2} e^{x^{3} + 27} d x

Wende U-Substitution an

= \int_{0}^{26} \frac{e ^{u}}{3} d u

Entferne die Konstante:

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

= \frac{1}{3} \cdot \int_{0}^{26} e^{u} d u

Nutze das gemeinsame Integral :

\int e^{u} d u = e^{u}

= \frac{1}{3} [e^{u}]_{0}^{26}

Berechne die Grenzen:

e^{26} - 1

= \frac{1}{3} (e^{26} - 1)
