integral from 0 to pi of 7cos^6(x)

解

\int_{0}^{π} 7 cos^{6} (x) d x

解

\frac{35 π}{16}

+1

十進法表記

6.87223 \dots

解答ステップ

\int_{0}^{π} 7 cos^{6} (x) d x

定数を除く:

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

= 7 \cdot \int_{0}^{π} cos^{6} (x) d x

積分換算を適用する

= 7 ([\frac{sin ( x ) cos ^{5} ( x )}{6}]_{0}^{π} + \frac{5}{6} \cdot \int_{0}^{π} cos^{4} (x) d x)

\int_{0}^{π} cos^{4} (x) d x = \frac{3 π}{8}

= 7 ([\frac{sin ( x ) cos ^{5} ( x )}{6}]_{0}^{π} + \frac{5}{6} \cdot \frac{3 π}{8})

簡素化

7 ([\frac{sin ( x ) cos ^{5} ( x )}{6}]_{0}^{π} + \frac{5}{6} \cdot \frac{3 π}{8}) : 7 ([\frac{1}{6} cos^{5} (x) sin (x)]_{0}^{π} + \frac{5 π}{16})

= 7 ([\frac{1}{6} cos^{5} (x) sin (x)]_{0}^{π} + \frac{5 π}{16})

限度を計算する:

0

= 7 (0 + \frac{5 π}{16})

簡素化

= \frac{35 π}{16}
