integral from 0 to 4 of (x^2-4x)

解

\int_{0}^{4} (x^{2} - 4 x) d x

解

- \frac{32}{3}

+1

十進法表記

- 10.66666 \dots

解答ステップ

\int_{0}^{4} x^{2} - 4 x 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_{0}^{4} x^{2} d x - \int_{0}^{4} 4 x d x

\int_{0}^{4} x^{2} d x = \frac{64}{3}

\int_{0}^{4} 4 x d x = 32

= \frac{64}{3} - 32

簡素化

\frac{64}{3} - 32 : - \frac{32}{3}

= - \frac{32}{3}
