What does n approach?. 0?. Infinity?. Something else?.
oh yea its infinity, I have to prove the answer using limi theorems, but I am lost because I do not know how to find the limit or break it up.
I think it is undefined because of the (-1)^n. You could rewrite You could try L'Hopital's rule. Frankly, we could say it is -1....1 Thus undefined. Perhaps someone else has another idea.
The book we are given says 0.
