Schritte zur Lösung

\int_{- 2}^{2} 4 - t^{2} d t

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} 4 d t - \int_{- 2}^{2} t^{2} d t

\int_{- 2}^{2} 4 d t = 16

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

= 16 - \frac{16}{3}

Vereinfache

16 - \frac{16}{3} : \frac{32}{3}

= \frac{32}{3}
