integral from 1 to 4 of |3-x|

解

\int_{1}^{4} ∣ 3 - x ∣ d x

解

\frac{5}{2}

解答ステップ

\int_{1}^{4} ∣ 3 - x ∣ d x

絶対数を排除する

= \int_{1}^{3} 3 - x d x + \int_{3}^{4} - 3 + x d x

\int_{1}^{3} 3 - x d x = 2

\int_{3}^{4} - 3 + x d x = \frac{1}{2}

= 2 + \frac{1}{2}

簡素化

2 + \frac{1}{2} : \frac{5}{2}

= \frac{5}{2}
