integral from-1 to 1 of (|x|-x^2)

解

\int_{- 1}^{1} (∣ x ∣ - x^{2}) d x

解

\frac{1}{3}

+1

十進法表記

0.33333 \dots

解答ステップ

\int_{- 1}^{1} ∣ x ∣ - x^{2} d x

絶対数を排除する

= \int_{- 1}^{0} - x - x^{2} d x + \int_{0}^{1} x - x^{2} d x

\int_{- 1}^{0} - x - x^{2} d x = \frac{1}{6}

\int_{0}^{1} x - x^{2} d x = \frac{1}{6}

= \frac{1}{6} + \frac{1}{6}

簡素化

\frac{1}{6} + \frac{1}{6} : \frac{1}{3}

= \frac{1}{3}
