integral from-7 to 3 of |x|

解

\int_{- 7}^{3} ∣ x ∣ d x

解

29

解答ステップ

\int_{- 7}^{3} ∣ x ∣ d x

絶対数を排除する

= \int_{- 7}^{0} - x d x + \int_{0}^{3} x d x

\int_{- 7}^{0} - x d x = \frac{49}{2}

\int_{0}^{3} x d x = \frac{9}{2}

= \frac{49}{2} + \frac{9}{2}

簡素化

\frac{49}{2} + \frac{9}{2} : 29

= 29
