integral from 1 to 4 of x-1

解

\int_{1}^{4} x - 1 d x

解

\frac{9}{2}

+1

十進法表記

4.5

解答ステップ

\int_{1}^{4} x - 1 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_{1}^{4} x d x - \int_{1}^{4} 1 d x

\int_{1}^{4} x d x = \frac{15}{2}

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

= \frac{15}{2} - 3

簡素化

\frac{15}{2} - 3 : \frac{9}{2}

= \frac{9}{2}
