Hi all.

Please take a look at this expression, where T is our variable (it represents temperature):

[tex]

C_v = 2\left( {\frac{{\hbar \omega }}{T}} \right)^2 \frac{{\exp \left( {\frac{{\hbar \omega }}{T}} \right)}}{{\left( {\exp \left( {\frac{{\hbar \omega }}{T}} \right) - 1} \right)^2 }}.

[/tex]

I have to evaluate this for [itex]T \rightarrow 0[/itex]. I would use L'Hopital, but isn't there an easier way? Because when I differentiate the nominator (the top), then I will end up with an expression like the original nominator, which wont help me.

Thanks in advance.

Sincerely,

Niles.
