Schritte zur Lösung

\int_{2}^{5} π (x^{2} - \frac{1}{5} x^{4}) d x

Entferne die Konstante:

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

= π \cdot \int_{2}^{5} x^{2} - \frac{1}{5} 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_{2}^{5} x^{2} d x - \int_{2}^{5} \frac{1}{5} x^{4} d x)

\int_{2}^{5} x^{2} d x = 39

\int_{2}^{5} \frac{1}{5} x^{4} d x = \frac{3093}{25}

= π (39 - \frac{3093}{25})

Vereinfache

π (39 - \frac{3093}{25}) : - π \frac{2118}{25}

= - π \frac{2118}{25}

\int_{0}^{\frac{1}{2}} arcsin^{2} (x) d x

\int_{2}^{4} x^{2} + 1 d x

\int_{- 2}^{1} x^{3} + x^{2} - 2 x d x

\int_{0}^{3} x (x^{2} + 2)^{2} d x

\int_{1}^{\infty} \frac{1}{x + x ^{2}} d x
