My book covers special integrating factors #mu# that are functions of only #x# or only #y#, but kinda glosses over how to find an integrating factor that is a function of #x# AND #y#. Example equation: #(2y^2 - 6xy)dx + (3xy - 4x^2)dy = 0# The integrating factor was #mu(x,y) = xy#, and the solution was #F(x,y) = x^2y^3 - 2x^3y^2 = C#. I was able to figure out what the integrating factor was, and solve the equation, but I...
