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{10}{3}

= \frac{10}{3}
