Hi all,
I have to show that the heat capacity can be expressed as
Cv = Nk(1+1/45(Om/T)^2 + ...)
where the internal energy is given as
E = NkT*(1-(Om/(3T)-1/45(Om/T)^2)
Normally I would just differentiate but if I do this I get something completely different - how to proceed any hints appreciated thanks in advance
Best regards
Magnus
