Hi

I'm just wondering, the limit of the signum function from the right side is 1 and the limit of the signum function from the left side is -1.

What do we say about the 2-sided limit? Do we say it doesn't exist?

It's ok, I saw a video on you tube.

I have found that the two-sided limit doesn't exist when the limits from each side differ.

thanks.
