integral from 1 to 2 of-x^2+4

解

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

解

\frac{5}{3}

+1

十進法表記

1.66666 \dots

解答ステップ

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

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

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

= - \frac{7}{3} + 4

簡素化

- \frac{7}{3} + 4 : \frac{5}{3}

= \frac{5}{3}
