integral from 3 to 4 of (x^2-9)

解

\int_{3}^{4} (x^{2} - 9) d x

解

\frac{10}{3}

+1

十進法表記

3.33333 \dots

解答ステップ

\int_{3}^{4} x^{2} - 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_{3}^{4} x^{2} d x - \int_{3}^{4} 9 d x

\int_{3}^{4} x^{2} d x = \frac{37}{3}

\int_{3}^{4} 9 d x = 9

= \frac{37}{3} - 9

簡素化

\frac{37}{3} - 9 : \frac{10}{3}

= \frac{10}{3}
