integral from-8 to 8 of (64-x^2)

解

\int_{- 8}^{8} (64 - x^{2}) d x

解

\frac{2048}{3}

+1

十進法表記

682.66666 \dots

解答ステップ

\int_{- 8}^{8} 64 - x^{2} d x

総和規則を適用する:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{- 8}^{8} 64 d x - \int_{- 8}^{8} x^{2} d x

\int_{- 8}^{8} 64 d x = 1024

\int_{- 8}^{8} x^{2} d x = \frac{1024}{3}

= 1024 - \frac{1024}{3}

簡素化

1024 - \frac{1024}{3} : \frac{2048}{3}

= \frac{2048}{3}
