If you approach a verticle asymptote from both sides, doesn't that end up not being a limit at all?
 
If YOU are approaching from both sides, YOU are split in two! Ouch!

Let's see if I've got this straight. pka will jab at me if I'm off again... :wink:

Which way does it go from each side? Both up? Both down? One each direction?

As long as we are talking about vertical asymptotes: For a one-sided limit, the limit IS +infinity or -infinity (whichever is appropriate). If it is the same from both sides, then the over-all limit exists and IS what the two one-sided limits are. If one is +infinity and one is -infinity, then the limit doesn't exist.

I hope I got my semantics right, this time.
 
The limit from the left is -infinity, the limit from the right is infinity. I wrote none for the limit from both sides.I think that's what you said anyway, lol. I wouldn't want to be torn apart now. I'll have to be more careful about my wording I guess, lol.
