0.64

Schritte zur Lösung

\int_{0}^{0.4} 2 (1 - x) d x

Entferne die Konstante:

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

= 2 \cdot \int_{0}^{0.4} 1 - x d x

Wende die Summenregel an:

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

= 2 (\int_{0}^{0.4} 1 d x - \int_{0}^{0.4} x d x)

\int_{0}^{0.4} 1 d x = 0.4

\int_{0}^{0.4} x d x = 0.08

= 2 (0.4 - 0.08)
