integral from 1 to 2 of 9/(x^2)

解

\int_{1}^{2} \frac{9}{x ^{2}} d x

解

\frac{9}{2}

+1

十進法表記

4.5

解答ステップ

\int_{1}^{2} \frac{9}{x ^{2}} d x

定数を除く:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 9 \cdot \int_{1}^{2} \frac{1}{x ^{2}} d x

べき乗則を適用する

= 9 [- \frac{1}{x}]_{1}^{2}

限度を計算する:

\frac{1}{2}

= 9 \cdot \frac{1}{2}

簡素化

= \frac{9}{2}
