\int_{2}^{6} π (x - 2)^{2} d x

Entferne die Konstante:

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

= π \cdot \int_{2}^{6} (x - 2)^{2} d x

Vereinfache

(x - 2)^{2} : x - 2

= π \cdot \int_{2}^{6} x - 2 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

= π (\int_{2}^{6} x d x - \int_{2}^{6} 2 d x)

\int_{2}^{6} x d x = 16

\int_{2}^{6} 2 d x = 8

= π (16 - 8)

= 8 π
