\int_{- 7}^{7} \frac{1}{2} (49 - x^{2}) d x

Entferne die Konstante:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int_{- 7}^{7} 49 - x^{2} 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

= \frac{1}{2} (\int_{- 7}^{7} 49 d x - \int_{- 7}^{7} x^{2} d x)

\int_{- 7}^{7} 49 d x = 686

\int_{- 7}^{7} x^{2} d x = \frac{686}{3}

= \frac{1}{2} (686 - \frac{686}{3})

Vereinfache

\frac{1}{2} (686 - \frac{686}{3}) : \frac{686}{3}

= \frac{686}{3}
