1. ## Epsilon Issues

What am I doing wrong with $\Epsilon$?

2. ## Re: Epsilon Issues

use \sum

$\sum$

yes, \Epsilon should work too but oh well.

3. ## Re: Epsilon Issues

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":
$E$.
