微分方程求解 (x^2y^3+xy)dy=dx
解微分方程 (x^2y^3+xy)dy=dx
x^2+xy+y^3=1,求dy/dx
dy/dx=(x+y^3)/(xy^2)
微分方程求解 (x^2y^3+xy)dy=dx
dy/dx=(x+y^3)/xy^2
常微分方程dy/dx=(x^3+xy^2)/y
求解微分方程 x^2*dy/dx=xy-y^2
求齐次微分方程dy/dx=y^2/xy-x^2
dy/dx=xy/x^2-y^2
dy/dx=1+x+y^2+xy^2
求通解:(xy-x^2)dy=y^2dx
dy/dx=y^2/(x-xy)是齐次方程吗
y/x=ln(xy) 求dy/dx(xy-y^2)/(xy+x^2)
1.dy/dx=(y-x)/(y+x)2.x^2*dy/dx=xy-y^2
(x^2)dy+(y^2)dx=dx-dy
式子转化:y^2+x^2(dy/dx)=xy(dy/dx)y^2+x^2(dy/dx)=xy(dy/dx) 原方程可写成dy/dx=y^2/(xy-x^2) 对怎么分离dy/dx和y^2/(xy-x^2) 能说下吗,
求微分方程dy/dx+2xy=3x
