Schritte zur Lösung

\int_{- 2}^{3} x^{3} - 7 x + 2 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^{3} d x - \int_{- 2}^{3} 7 x d x + \int_{- 2}^{3} 2 d x

\int_{- 2}^{3} x^{3} d x = \frac{65}{4}

\int_{- 2}^{3} 7 x d x = \frac{35}{2}

\int_{- 2}^{3} 2 d x = 10

= \frac{65}{4} - \frac{35}{2} + 10

Vereinfache

\frac{65}{4} - \frac{35}{2} + 10 : \frac{35}{4}

= \frac{35}{4}

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

\int_{0}^{π} x^{3} sin (3 x) d x

\int_{1}^{4} (- 3 x) d x

\int_{0}^{4} \frac{1}{( x - 1 ) ^{\frac{1}{3}}} d x

\int_{1}^{\infty} \frac{2}{3 x + 4} d x
