0.25

Schritte zur Lösung

\int_{1}^{3.5} \frac{2}{25} (x - 1) d x

Entferne die Konstante:

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

= \frac{2}{25} \cdot \int_{1}^{3.5} x - 1 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

= \frac{2}{25} (\int_{1}^{3.5} x d x - \int_{1}^{3.5} 1 d x)

\int_{1}^{3.5} x d x = 5.625

\int_{1}^{3.5} 1 d x = 2.5

= \frac{2}{25} (5.625 - 2.5)

Vereinfache

\frac{2}{25} (5.625 - 2.5) : 0.25

= 0.25
