integral from-1 to 2 of x-1

解

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

解

- \frac{3}{2}

+1

十進法表記

- 1.5

解答ステップ

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

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

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

= \frac{3}{2} - 3

簡素化

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

= - \frac{3}{2}
