Schritte zur Lösung

\int_{0}^{1} 2 π (2 - y) \cdot 8 y^{2} d y

Entferne die Konstante:

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

= 2 π 8 \cdot \int_{0}^{1} (2 - y) y^{2} d y

Vereinfache

= 16 π \cdot \int_{0}^{1} (2 - y) y^{2} d y

(2 - y) y^{2} : 2 y^{2} - y^{3}

= 16 π \cdot \int_{0}^{1} 2 y^{2} - y^{3} d y

Wende die Summenregel an:

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

= 16 π (\int_{0}^{1} 2 y^{2} d y - \int_{0}^{1} y^{3} d y)

\int_{0}^{1} 2 y^{2} d y = \frac{2}{3}

\int_{0}^{1} y^{3} d y = \frac{1}{4}

= 16 π (\frac{2}{3} - \frac{1}{4})

Vereinfache

16 π (\frac{2}{3} - \frac{1}{4}) : \frac{20 π}{3}

= \frac{20 π}{3}
