### How to enter the "big epsilon" in LaTeX

There are two kinds of epsilons in LaTeX, \(\epsilon\) and \(\varepsilon\), which can be entered as "\epsilon" and "\varepsilon" respectively. So how about the "big epsilon" \(\mathcal{E}\) which occurs often as the symbol for "energy functional"? It turns out, it's not an epsilon, but a curved letter "E". To enter it in LaTeX, simply do "\mathcal{E}".

Thank u!

I just googled big epsilon latex as everyone else. Thanks !

Thanks, i am thinking big epsilon too !

That's a Roman E in script, not a 'big epsilon'. A capital epsilon is indistinguishable from an E, and presumably you'd want it to appear in the same font family as your other Greek letters.

Thank you so much! I don't care where it comes from, I'm no linguist! That's the character I need.

Many thanks for this. Irrespective of what it is typographically it is a better version of the symbol for electric field.
