Schritte zur Lösung

\int_{- 1}^{3} 8 - 4 y^{2} d y

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}^{3} 8 d y - \int_{- 1}^{3} 4 y^{2} d y

\int_{- 1}^{3} 8 d y = 32

\int_{- 1}^{3} 4 y^{2} d y = \frac{112}{3}

= 32 - \frac{112}{3}

Vereinfache

32 - \frac{112}{3} : - \frac{16}{3}

= - \frac{16}{3}

\int_{0}^{2 π} t^{2} 2 d t
