integral from 1 to 4 of (x-3)^2

解

\int_{1}^{4} (x - 3)^{2} d x

解

3

解答ステップ

\int_{1}^{4} (x - 3)^{2} d x

拡張

(x - 3)^{2} : x^{2} - 6 x + 9

= \int_{1}^{4} x^{2} - 6 x + 9 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^{2} d x - \int_{1}^{4} 6 x d x + \int_{1}^{4} 9 d x

\int_{1}^{4} x^{2} d x = 21

\int_{1}^{4} 6 x d x = 45

\int_{1}^{4} 9 d x = 27

= 21 - 45 + 27

簡素化

= 3
