dy/dx+(2/x)y=3x^2*y^(4/3)

dy/dx=2y/x+3x/2y 2*x*y^2（dy／dx）- x^3（dy／dx）=2y^3 dy/dx=(x^4+y^3)/xy^2 dy/dx-2y/(1+x)=(x+1)^3 微分方程 dy/dx=(e^y+3x)/x^2 dy/dx-y/x=x^2 从(dx)/(dy)=1/y '导出：(d^2x)/(dy^2)=-y''/(y')^3 (x^2)dy+（y^2)dx=dx-dy y^3+4y^2+11y=x-13 求导 dy/dx 怎么求呀? dy/dx+(2/x)y=3x^2*y^(4/3) dy/dx 3x^2+4y^3-2x-5y+1=0 求解一道微分方程题​x*y^3*dy+(y^4-x^2)*dx=0
