Schritte zur Lösung

\int_{1}^{2} x^{2} - 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_{1}^{2} x^{2} d x - \int_{1}^{2} 1 d x

\int_{1}^{2} x^{2} d x = \frac{7}{3}

\int_{1}^{2} 1 d x = 1

= \frac{7}{3} - 1

Vereinfache

\frac{7}{3} - 1 : \frac{4}{3}

= \frac{4}{3}
