\int_{0}^{1} 2 π (x + 5) x^{2} d x

Entferne die Konstante:

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

= 2 π \cdot \int_{0}^{1} (x + 5) x^{2} d x

(x + 5) x^{2} : x^{3} + 5 x^{2}

= 2 π \cdot \int_{0}^{1} x^{3} + 5 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

= 2 π (\int_{0}^{1} x^{3} d x + \int_{0}^{1} 5 x^{2} d x)

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

\int_{0}^{1} 5 x^{2} d x = \frac{5}{3}

= 2 π (\frac{1}{4} + \frac{5}{3})

Vereinfache

2 π (\frac{1}{4} + \frac{5}{3}) : \frac{23 π}{6}

= \frac{23 π}{6}
