(NCERT)(b)y+x(dy)/(dx)=x-y(dy)/(dx)

x(dy)/(dx)=y

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

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

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

(y-x(dy)/(dx))=3(1-x^(2)(dy)/(dx))

Solve: y-x(dy)/(dx)=x+y(dy)/(dx)

If y=x log((x)/(a+bx)), thenx ^(3)(d^(2)y)/(dx^(2))= (a) x(dy)/(dx)-y (b) (x(dy)/(dx)-y)^(2)y(dy)/(dx)-x(d)(y(dy)/(dx)-x)^(2)

If y=xlog(x/(a+b x)),t h e nx^3(d^2y)/(dx^2)= (a) x(dy)/(dx)-y (b) (x(dy)/(dx)-y)^2 y(dy)/(dx)-x (d) (y(dy)/(dx)-x)^2

Solve the following differential equations: (dy)/(dx)=1+x+y+x y (ii) y-x(dy)/(dx)=a(y^2+(dy)/(dx))
