Lösung

18

Schritte zur Lösung

\int_{0}^{π} 9 sin (x) d x

Entferne die Konstante:

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

= 9 \cdot \int_{0}^{π} sin (x) d x

Nutze das gemeinsame Integral :

\int sin (x) d x = - cos (x)

= 9 [- cos (x)]_{0}^{π}

Berechne die Grenzen:

2

= 9 \cdot 2

Vereinfache

= 18
