Have come across a limits questions I am having trouble with.
I get stuck after that...I know that but not sure what to do when the limit is for , and also the first part becomes undefined which is not the answer - the limit exists. Any tips?
EDIT: sorry I just realised that and now it is simple - so Q solved!
Hehe no worries....it's typical that I can't figure out a question so come onto here and finally go and sort out all the latex code for my question only to suddenly see the answer staring me in the face...did the same thing last night but figured it out before I hit submit thread!
