integral from-2 to-1 of (2-3x^2)

解

\int_{- 2}^{- 1} (2 - 3 x^{2}) d x

解

- 5

解答ステップ

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

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

\int_{- 2}^{- 1} 3 x^{2} d x = 7

= 2 - 7

簡素化

= - 5
