Schritte zur Lösung

\int_{0}^{1} 2 x (e^{x^{2}} - 1) d x

Entferne die Konstante:

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

= 2 \cdot \int_{0}^{1} x (e^{x^{2}} - 1) d x

Wende U-Substitution an

= 2 \cdot \int_{0}^{1} \frac{e ^{u} - 1}{2} d u

Entferne die Konstante:

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

= 2 \cdot \frac{1}{2} \cdot \int_{0}^{1} e^{u} - 1 d u

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= 2 \cdot \frac{1}{2} (\int_{0}^{1} e^{u} d u - \int_{0}^{1} 1 d u)

\int_{0}^{1} e^{u} d u = e - 1

\int_{0}^{1} 1 d u = 1

= 2 \cdot \frac{1}{2} (e - 1 - 1)

Vereinfache

2 \cdot \frac{1}{2} (e - 1 - 1) : e - 2

= e - 2
