展开 (2xy^5-y)dx+2xdy

解答

展开

(2 x y^{5} - y) d x + 2 x d y

2 x y^{5} d x - y d x + 2 x d y

求解步骤

(2 x y^{5} - y) d x + 2 x d y

乘开

d x (2 x y^{5} - y) : 2 x y^{5} d x - y d x

= 2 x y^{5} d x - y d x + 2 x d y

e x p an d 18 x^{2} - (24 x + 4) ln (x)

e x p an d \frac{( x - 2 ) 6 sin ( x )}{∣ x - 2 ∣}

e x p an d \frac{e ^{x} - 1 - x}{x ( e ^{x} - 1 )}

e x p an d a (1, 3, 4) B (2, 4, - 1)

e x p an d \frac{x - 3}{( x + 1 ) ( x - 6 )}
