30

Schritte zur Lösung

\int_{- 3}^{3} 5 x^{3} + 2 x^{2} + 6 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_{- 3}^{3} 5 x^{3} d x + \int_{- 3}^{3} 2 x^{2} d x + \int_{- 3}^{3} 6 x d x - \int_{- 3}^{3} 1 d x

\int_{- 3}^{3} 5 x^{3} d x = 0

\int_{- 3}^{3} 2 x^{2} d x = 36

\int_{- 3}^{3} 6 x d x = 0

\int_{- 3}^{3} 1 d x = 6

= 0 + 36 + 0 - 6
