integral from 0 to 2 of integral from 0 to sqrt(2-x^2 of)18xy

解

\int_{0}^{2} \int_{0}^{2 - x^{2}} 18 x y d y d x

解

0

解答ステップ

\int_{0}^{2} \int_{0}^{2 - x^{2}} 18 x y d y d x

\int_{0}^{2 - x^{2}} 18 x y d y = 9 x (- x^{2} + 2)

= \int_{0}^{2} 9 x (- x^{2} + 2) d x

\int_{0}^{2} 9 x (- x^{2} + 2) d x = 0

= 0
