I tried to put a mathematical expression into an
answer hint but that did not work (the hint just
included the untexed expression.) Is there a way to get around this?
If you use
END_HINTthen TeX will be processed in the same way that it is with BEGIN_TEXT/END_TEXT.
(This is somewhat recent, since about version 2.3 of PG.)
BEGIN_HINT is translated into the following, uglier, construction which
could also be used:
HINT(EV3(<<'END_HINT')); hint stuff END_HINT
