this commit fixes quite possible the stupidest thing i've ever done. 
wondering where messages like this

	$GlobalSets[1] (ID Sec9.2ParametricEq) not defined -- skipping
	at /ww/webwork/webwork2/lib/WeBWorK/ContentGenerator/Hardcopy.pm
	line 286.

were coming from?
the answer is:

	$GlobalSets[1] = undef;

which is a line i put in there for testing and never removed. i am very
sorry. :-(
