Re: A troubling generating function

Yes,you are right,but the same method is used. And the answer is similar.

Actually,I just calculated the limit and it doesn't exist.

Re: A troubling generating function

That is what 1) is asking. You are getting for the limit infinity?

Yes,I am getting infinity for our limit.

Re: A troubling generating function

I have figured out why. In gar's limit the roots of n cancel out,so it exists and that is not the case with our limit.
