| Hello
everyone. We just installed the WeBWorK system last month and we have
been checking and fixing errors. There is a strange thing about every
on-the-fly graphic problem here: it does not plot curves except for the
two end-points (even for constant function like y=1). There were no
error messages. It appears like that the plot_functions just take the
function "1 for x in [1,2]" for a function "y=1 defined at 1 and 2
only".
I did not find similiar topics in this forum. Does anyone have any suggestions? Thanks a lot.
