integral from 0 to 0.2 of (x^6)/(1+x^7)

解

\int_{0}^{0.2} \frac{x ^{6}}{1 + x ^{7}} d x

解

1.82856 E - 6

解答ステップ

\int_{0}^{0.2} \frac{x ^{6}}{1 + x ^{7}} d x

u置換積分法を適用する

= \int_{1}^{1.0000128} \frac{1}{7 u} d u

定数を除く:

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

= \frac{1}{7} \cdot \int_{1}^{1.0000128} \frac{1}{u} d u

共通積分を使用する:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{7} [ln ∣ u ∣]_{1}^{1.0000128}

簡素化

= 0.14285 \dots [ln ∣ u ∣]_{1}^{1.0000128}

限度を計算する:

0.00001 \dots

= 0.14285 \dots \cdot 0.00001 \dots

簡素化

= 1.82856 E - 6
