Beginning with , multiply by to obtain:
The limit on the left is 1, and the limit on the right is 2. Hence the limit of the product is 2.
find the limit or prove it does not exist
just pluging this into my calculator it looks like the limit is 2 but i can't figure out how to get this... i should mention it looks like there is no slope there, i know that means that there is no derivative there but i forgot if that also means the limit is undefined?
