How do I make "E" in this equation a small cap?
$x^E$

To switch fonts in math mode you often use a command like \mathit (for italic) or \mathrm (for roman). But there's no \mathsc command. So just use \textsc.
$x^{\textsc{e}}$
Note that \textsc{E} will give a capital E that is roughly the same height as the normal shape capital E. In general, if you want a small capital E, use \textsc{e}.

6Is there a reason why you wouldn't simply use
$x^{\textsc{e}}$? Mar 9, 2011 at 12:48 -
2@Niel: the reason I didn't was that I didn't know you could do that! For some reason I thought that
\textscwould require LR mode. I've edited to reflect your simplification. Mar 9, 2011 at 12:54 -
1If you want to have slanted small-caps in math mode, you have to fake it:
\mbox{\footnotesize{\textit{E}}}Nov 12, 2018 at 17:13 -

@Marian, the
\mboxensures some nice spacing around the symbol. Try${\E}^x$with and without the\mbox, where\Eis the symbold defined as above. But I'm no expert - more information here. Nov 19, 2018 at 20:28
The above mentioned $x^{\textsc{e}}$ works in basic situations, but it has the drawback that the font used will depend on the current text font in the environment. For example, \texttt{ ... $x^{\textsc{e}}$ ... } typesets the small capital E in the typewriter font. This is usually undesirable for a mathematical symbol. The problem is most prominent when the surrounding text is bold (such as in a heading): there are no bold extended small caps fonts in the standard Computer Modern font collection, hence the e in \section{ ... $x^{\textsc{e}}$ ... } will come out as bold lower case. So, if you want a general-purpose macro, it is better to use
$x^{\normalfont\textsc{e}}$
You can define
\newcommand{\mathsc}[1]{{\normalfont\textsc{#1}}}

1With
amsmatha better way would be\text{\normalfont\scshape#1}(assuming, by way of contradiction, that the OP really has a problem, which it isn't).– egregJul 23, 2012 at 16:54 -
3The poster of the original question most likely does not have a problem any more, given that it is over a year old. However, other people may have problems. Note that this question turns up as the #1 Google hit for “latex math small caps”, so it is worthwhile to document any relevant info here. And yes, I encountered this very problem in a real-world situation, it is not made up. Jul 23, 2012 at 17:29

Just a side note: If in beamer,
\normalfont\textsc{e}does not work but\textrm{\textsc{e}}does.– tvkOct 23, 2018 at 0:15 -
2Or maybe
\textnormal{\textsc{e}}... See: tex.stackexchange.com/questions/70632/…– PatrickTDec 12, 2018 at 15:48
My chosen solution which works fine is
\newcommand{\xE}{\ensuremath{ x^{\mbox{\tiny{E}}} }}

$x^E$just good enough? It typesetsEin the smaller script style.$x^E$is still far too big and aggressive for me.
