`(x^2+y^2)dy/dx`=xy

(x^2y^3+xy)dy=dx

The differential equations of all circle touching the x-axis at orgin is (a) (y^(2)-x^(2))=2xy((dy)/(dx)) (b) (x^(2)-y^(2))(dy)/(dx)=2xy ( c ) (x^(2)-y^(2))=2xy((dy)/(dx)) (d) None of these

(1-x^(2))(dy/dx)+xy=xy^(2)

y^2+x^2(dy)/(dx)=x y(dy)/(dx)

The solution of differential equation (1-xy + x^(2) y^(2))dx = x^(2) dy is

The solution of the differential equation (x^2y^2-1)dy+2xy^3dx=0 is

y^2dx+(x^2-xy+y^2)dy=0

Solve (x^(2) + y^(2))(dy)/(dx) = 2xy

The solution x^2( dy )/( dx) = x^2 + xy + y^2 is :

Solve: y(2xy+1)dx+x(1+2xy+x^2y^2)dy=0
