Hello :)
I'm not at all a specialist in condensed matter, nor do I understand much of its basics. I'm nevertheless a 1st year physics student who has a summer project on some aspect of modes in graphene and I would like to understand why the mathematics I was using this summer was the one...
Maybe the 2\pi +1 and so on wasn't so clear.
I really meant ''x over n'' in sin(x/n), but I used LaTeX terminology for ''pi'' 2\pi is really 2*pi.
I don't think I fooled many of you, but just in case... :)
Hi and thank you for reading this.
I'm learning to use mathematica and among those things I'm trying to do, is to define a function that can count for me, say, the number of positive zeros less than a given number Z of a familly of function.
For exemple, let f_n(x) = sin(x/n) for any...
