1. I need to find a condition that the equation will have a integration factor from the shape K(x*y).
(K-integration factor sign)
2.the eq from the shape M(x,y)dx+N(x,y)dy=0 ,not have to be exact!3. i tried to open from the basics. d(k(x*y)M(x,y))/dy=d((k(x*y)N(x,y))/dx.
and i used the fact that d(k(x,y))/dy is x (exc. for dx)/
im hoping i was clear enough , thanks and sorry for my bad english.
