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

解

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

解

- \frac{13}{3}

+1

十進法表記

- 4.33333 \dots

解答ステップ

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

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

\int_{2}^{3} x^{2} d x = \frac{19}{3}

= 2 - \frac{19}{3}

簡素化

2 - \frac{19}{3} : - \frac{13}{3}

= - \frac{13}{3}
