The integrating factor of (dy)/(dx) +2 y/x = e^(4x) is :

(dy)/(dx)+(y)/(xlogx)=(sin2x)/(logx)

x(dy)/(dx)+y=xlogx

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

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

The integrating factor for (dy)/(dx) - 2y tan x = cos x is :

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

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

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

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