integral from 0 to 5 of integral from 0 to 6 of uv(1)

解答

\int_{0}^{5} \int_{0}^{6} uv (1) d v d u

225

求解步骤

\int_{0}^{5} \int_{0}^{6} uv (1) d v d u

\int_{0}^{6} uv (1) d v = u \cdot 18

= \int_{0}^{5} u \cdot 18 d u

\int_{0}^{5} u \cdot 18 d u = 225

= 225

\int \int \frac{6}{7} x^{\frac{6}{7}} d x d x

\int_{0}^{1} \int_{0}^{- 2 x + 2} 2 e^{- x - 2 y} d y d x

\int \int sin (x) cos (y) d x d y

\int \int e^{- (9 x^{2} + y^{2})} d A

\int \int e^{3 x} d x d x
