how do i know a given nth order differential equation is linear or not?
both for ODE as well as PDE.
okay i figured it out.
there should not be product of function and its derivatives
neither the function nor its derivatives occur at any power other than the first power.
m i right?
or are there any other conditions other than these?
You are right.
I was going to suggest that you look at the definition of "linear differential equation"! I am pleased that you have already done that!
