Hi,
I tripped over this and can't explain it; I hope someone here will
show me what I am missing:
Using this source:
=====
\newcommand{\dx}{\rm dx}
$\Phi(\dx_i)=dx_i$.
=====
the output has both "dx_i"s the same ("upright", including the
subscript). If I use
$\Phi({\dx}_i)=dx_i$.
the output is what I would expect (the second "dx", and both "i"s are
"italic"). I'm clearly missing or forgetting something about the way
(La)TeX operates.
Clues?
Thanks for the help.
Regards,
Justin
