Remake of Infinity thread?

[ljw5021]

I wanted to comment and the thread is closed, so I wondered if other people felt the same way :P.

If you'll read through the thread, you'll notice one error in most everyones answer. They assume infinity is a number.

Infinity is a concept...a theory. It is not a number. This is why we need L'Hopital's rule to evaluate situations such as limits involving infinity over infinity, or zero over zero.

Even in situations such as infinity times zero, or one to the infinity power, you need to manipulate the current evaluation of the limit in order to work with it.

Oh well, reply if you have another situation or problem. I'm only going on Calc 2 knowledge so maybe I'm missing something.
