人気のある微分積分 >

integral from 0 to 1 of-5x5^x

解

\int_{0}^{1} - 5 x 5^{x} d x

解

- \frac{5 ( 5 ln ( 5 ) - 4 )}{ln ^{2} ( 5 )}

+1

十進法表記

- 7.81223 \dots

解答ステップ

\int_{0}^{1} - 5 x \cdot 5^{x} d x

定数を除く:

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

= - 5 \cdot \int_{0}^{1} x \cdot 5^{x} d x

部分積分を適用する

= - 5 [\frac{5 ^{x} x}{ln ( 5 )} - \int \frac{5 ^{x}}{ln ( 5 )} d x]_{0}^{1}

\int \frac{5 ^{x}}{ln ( 5 )} d x = \frac{5 ^{x}}{ln ^{2} ( 5 )}

= - 5 [\frac{5 ^{x} x}{ln ( 5 )} - \frac{5 ^{x}}{ln ^{2} ( 5 )}]_{0}^{1}

限度を計算する:

\frac{5 ln ( 5 ) - 4}{ln ^{2} ( 5 )}

= - 5 \cdot \frac{5 ln ( 5 ) - 4}{ln ^{2} ( 5 )}

簡素化

= - \frac{5 ( 5 ln ( 5 ) - 4 )}{ln ^{2} ( 5 )}
