Error computing limits as x -> inf

[Chris Pem10]

I'd prefer that the calc not give me just enough rope to hang myself. If the HOME environment is not capable of performing limits at infinity, perhaps the calc should auto-magically substitute 1E50 for inf. And by substitution, I mean flash a warning that the substitution is happening and why.

It makes zero sense to have a working limit function in the CAS and a second version in HOME that fails. You cannot assume that the student will be smarter than the machine and capable of working around its quirks.
