# [texhax] Problem with amsmath and wasysym

hi, zac,

When I tried to run latex on a file with amsmath and wasysym, I got the
following error.  I'm not a LaTeX expert, but I did deduce that wasysym
defines \iint and so does amsmath and they conflict.  How should I solve
this if I want to include both these files in my document?

first, decide which form of \iint you want to use
(if any).  load the other package first, and then
\let\iint\relax
that will make latex think that \iint hasn't been
defined, and when the version you want comes along
in the package you've chosen, the desired \iint
will be defined with no problem.

\let\otheriint\iint
\let\iint\relax
then you can use \otheriint (you can substitute a
name you like better) and \iint both in suitable
circumstances.
