Schritte zur Lösung

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

\int_{- 2}^{2} x^{2} d x = \frac{16}{3}

\int_{- 2}^{2} x d x = 0

= \frac{16}{3} + 0

Vereinfache

= \frac{16}{3}

\int_{- 1}^{2} (x^{2} + x - 4) d x

\int_{7}^{25} x^{2} \frac{x - 7}{162} d x

\int_{1}^{e} (1 + x^{2}) ln (x) d x

\int_{0}^{1} 12 x e^{x} d x

\int_{0}^{\frac{π}{4}} \frac{5}{cos ( x )} d x
