Schritte zur Lösung

\int_{- 2}^{3} x^{2} + 5 x + 1 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}^{3} x^{2} d x + \int_{- 2}^{3} 5 x d x + \int_{- 2}^{3} 1 d x

\int_{- 2}^{3} x^{2} d x = \frac{35}{3}

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

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

= \frac{35}{3} + \frac{25}{2} + 5

Vereinfache

\frac{35}{3} + \frac{25}{2} + 5 : \frac{175}{6}

= \frac{175}{6}

\int_{0}^{π} (x + 1) sin (n x) d x

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

\int_{4}^{9} \frac{1}{3 x} d x

\int_{\frac{π}{6}}^{\frac{π}{2}} x cos (x) d x

\int_{0}^{π} cos (\frac{1}{2} x) d x
