Thanks, Atrophy. 'Nother question.
So, the text book I'm using vaguely teaches us that any point can have a limit (except the certain specific exceptions), and that's all fine and dandy, until it asks us to fine all the limits on a graph, and there are no existing, er, hole-based limits (by hole, I mean the point where a function can't exist) on the graphs, Ought I just put "No Limits"? Or should I list the limits that don't exist and say every other point has a limit? Or can real points even have limits? My calc teacher's been gone the past days, and the sub hasn't got a clue.
Related: Say you have one of the cases where a limit can't exist, such as on a vertical asymptote, and part of the problem states that that point has a value. Does that value become the limit, even though it wouldn't exist normally?
Semi-Related: My calc teacher was (when he was here) teaching the class by teaching us how to use a TI-89. Problem is, I don't have a TI-89.
