What am I doing wrong with $\Epsilon$?
Follow Math Help Forum on Facebook and Google+
use \sum $\sum$ yes, \Epsilon should work too but oh well.
Sime implementations of TeX don't bother with uppercase (or even lowercase) Greek if they match the Roman versions. $\sum$ is not upppercase epsilon anyway, it's uppercase Sigma: $\Sigma$.
$\epsilon$ Don't use the capital E. This particular implementation of Latex does not have a "capital epsilon" perhaps because it is identical to the Roman "E": $E$.
