## anonymous 5 years ago hi there, i need some help with an equation includes n'',(n')^2,n can any one help me?

1. anonymous

Is n a function? If so then what you are describing a differential equation, which can be pretty gnarly to solve.

2. anonymous

thanx for ur time, yes n is a function, like y(x), its n($\phi$), is there any general procedure to solve this? what kind of DE is this?

3. anonymous

Looks like a second-order ordinary non-linear DE, I'm not positive, though.
