" 1."(dy)/(dx)=(x^(2)+y^(2))/(2xy)

(dy)/(dx)=(x^(2)-y^(2))/(xy)

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

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

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

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

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

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
