\textrm in math in superscript

[Jan Van den Bussche]

The nice thing of using \textrm in math mode (as opposed to \mathrm) is
that it adapts automatically to the surrounding environment. For example,
if I define the following alternative to \cos:

\newcommand{\mycos}{\mathop{\textrm{cos}}}

and I write

\bfseries $\mycos x$

then the "cos" will be bold in accordance with the surrounding environment
(the x will not, but that's another story).

Now my problem is with using the same thing superscripted (or subscripted).
If I write

$\textrm{a}^\textrm{b}$

the b is as large as the a which is ugly. I can manually fix this
by writing

$\textrm{a}^\textrm{\scriptsize b}$

and this looks just fine. But now suppose I want to put this in a macro and
use it everywhere:

\newcommand{\mymacro}{\textrm{a}^\textrm{\scriptsize b}}

However, if I now write

\footnotesize $\mymacro$

then the b is again too large: it is still in \scriptsize, because I manually
told it to be so. This is ugly because superscripts in a surrounding
\footnotesize environment are supposed to be in \scriptscriptsize.

How can I solve this, i.e., how can I define \mymacro so that the b always has
the appropriate size?

Thanks,

\usepackage{amstext}
...

$\textrm{a}^{\text{\textrm{b}}}$

Of course it is _wrong_ to abuse the system like this so that you get
bold in a nold environment. If you want a contect in which the text and
the math are both bold, go {\bfseries \boldmath ..... }

Something similar. I recently tried to typeset a few pages in sans serif,
including super/subscripts:

\sffamily\Large ... Na$^2+$ ...

There are a large number of chemical superscripts. What is the recommended
way of making the superscript also sans serif? Is there a package which
does that?

.. Na\textsuperscript{2+}

(I would define a shorter alias.)

A more complete solution is to define a sans-serif "math version"
in analogy with boldmath... except that the sans versions of the
math italic fonts don't exist.

More practical is to employ \everymath{\fam\sffam}... but no \sffam in LaTeX.
So use this:

\newcommand\everymathfont[1]{\ensuremath{#1{\xdef\emfTemp
{\everymath{\fam\the\fam\relax}}}}\emfTemp
}

..

\large \sf \everymathfont{\mathsf}
