Well,u could be doing some inventing.That's what it would be.Take a function differentiate it 7 times,square the result,multiply everything with wierd functions and add more terms to the equation and set everything to zero.And then try to solve the equation to find the original function.I say it's nonsense,don't u think so??
U mean draw the integral curves/surfaces??It's pretty difficult to graph some function u don't know,wouldn't u say so??
Daniel.

What I'm saying is are there any distinct "signiture" DE graphs?
I am saying the opposite of you last statement, I am saying looking at a surface first then saying ah yes, differential equation over here! though, i really dont need to deal with 3d, 2d is sufficient
