Talk:PHZ3400 Midterm Two Solution

Someone wrote Failed to parse (unknown function "\varepilon"): {\displaystyle Z = \sum_{n}^{\infty} \mathbf{\varepilon}^{-\beta E_n} \;} for the partition function for #1. I have $Z=\sum _{n}^{\infty }\mathbf {e} ^{-\beta E_{n}}\;$. Which is correct? KimberlyWynne 23:35, 15 April 2009 (EDT)
