\int_{0}^{5} π (25 x^{2} - x^{4}) d x

Entferne die Konstante:

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

= π \cdot \int_{0}^{5} 25 x^{2} - x^{4} 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_{0}^{5} 25 x^{2} d x - \int_{0}^{5} x^{4} d x)

\int_{0}^{5} 25 x^{2} d x = \frac{3125}{3}

\int_{0}^{5} x^{4} d x = 625

= π (\frac{3125}{3} - 625)

Füge

\frac{3125}{3} - 625

zusammen:

\frac{1250}{3}

= π \frac{1250}{3}
