Schritte zur Lösung

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

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

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

= \frac{16}{3} + 0

Vereinfache

= \frac{16}{3}

\int_{1}^{3} \frac{1}{x - 1} d x

\int_{- 5}^{c o s (x)} \frac{1}{t ^{2} - 1} d t

\int_{- 2}^{2} (∣ x ∣ + x) e^{∣ x ∣} d x

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

\int_{7}^{8} (\frac{3}{x ^{2}} - 1) d x
