Hi!

I have a question that may be simple for you experts...

How to make HP Prime show that a given limit does not exist?

For example, I tried limit of x/(x-3) as x approaches 3+ and I get ∞. As x approached 3-, I get -∞. But as x approaches 3 (not one-sided limit), I get +-∞... I would like it to show there is no limit since one-sided limits are differents.

Other example:

Limit of SQ(x-2) as x approaches 2-

It gives me 0, when I would like to see that there is no real number.

Thanks in advance.
