Hello
I stopped at this one :S
How to solve this one ?!!!
What I know:
Exact / Separable / Homogeneous
All of them are failed
am thinking about substituting
But those squares make my life hard
If it is x+y it would be easy ..

Not quite sure what you mean here. The solution to any differential equation is obtained essentially by integrating. In addition, you can usually (perhaps always?) convert a DE into an equivalent integral equation if you wish. Integral equations have technical advantages over differential equations, especially with regard to the space of functions you consider for solutions (no differentiability required!)So the differential equations are the same as the integrals.
Sometimes an analytical solution is not known. That might not mean that it's impossible to solve, just that we don't know what the solution is. In those cases, we usually hand it off to a computer.Sometimes its impossible to solve it?
