+1

Dezimale

- 0.40600 \dots

Schritte zur Lösung

\int_{- \infty}^{- 2} x e^{x} d x

Berechne das unbestimmte Integral:

\int x e^{x} d x = e^{x} x - e^{x} + C

Berechne die Grenzen:

\int_{- \infty}^{- 2} x e^{x} d x = - \frac{3}{e ^{2}} - 0

= - \frac{3}{e ^{2}} - 0

Vereinfache

= - \frac{3}{e ^{2}}
