Wende U-Substitution an

= \int_{0}^{x} e^{u} x d u

Entferne die Konstante:

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

= x \cdot \int_{0}^{x} e^{u} d u

Nutze das gemeinsame Integral :

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

= x [e^{u}]_{0}^{x}

Berechne die Grenzen:

e^{x} - 1

= x (e^{x} - 1)

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

\int_{0}^{2 π} 6 x^{2} cos (x) d x

\int_{- 6}^{0} (5 + 36 - x^{2}) d x

\int_{- 5}^{5} ln (x + 6) d x

\int_{- 2}^{0} - 3 x d x
