WeBWorK – how to enter infinity

Hi everyone,

It seems that entering “infinity” in WeBWorK can vary from problem to problem – but the most common versions are:

infty, -infty

infinity, -infinity

Inf, -Inf

I think the problems in this set prefer “infinity” and “-infinity”.

I was unaware of these variations – my apologies!  Let me know if you are still having trouble.
