And another in the Diff Eq series: Homogeneous Differential Equations
The main weakness in this page is no explanation of why they are "Homogeneous". I played with linking f(zx,zy) = z^n f(x,y) to dy/dx=F(x/y) form but failed. If anyone knows a user-friendly way of explaining why "Homogeneous" that would be nice.
Comments, suggestions and error checking welcome.
