Schritte zur Lösung

\int_{2}^{5} x^{3} - 3 x^{2} + x 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

= \int_{2}^{5} x^{3} d x - \int_{2}^{5} 3 x^{2} d x + \int_{2}^{5} x d x

\int_{2}^{5} x^{3} d x = \frac{609}{4}

\int_{2}^{5} 3 x^{2} d x = 117

\int_{2}^{5} x d x = \frac{21}{2}

= \frac{609}{4} - 117 + \frac{21}{2}

Vereinfache

\frac{609}{4} - 117 + \frac{21}{2} : \frac{183}{4}

= \frac{183}{4}

\int_{0}^{\frac{π}{2}} θ^{2} d θ

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

\int_{1}^{2} 10 x d x

\int_{1}^{8} \frac{5}{x} d x

\int_{- \frac{1}{8}}^{\frac{1}{8}} sin (2 p i x) d x
