integral from-3 to 3 of (5-|x|)

解

\int_{- 3}^{3} (5 - ∣ x ∣) d x

解

21

解答ステップ

\int_{- 3}^{3} 5 - ∣ x ∣ d x

絶対数を排除する

= \int_{- 3}^{0} 5 - (- x) d x + \int_{0}^{3} 5 - x d x

\int_{- 3}^{0} 5 - (- x) d x = \frac{21}{2}

\int_{0}^{3} 5 - x d x = \frac{21}{2}

= \frac{21}{2} + \frac{21}{2}

簡素化

\frac{21}{2} + \frac{21}{2} : 21

= 21
