Hi everyone. First post here. I am having a bit of trouble in my Real Class. I am going back to school and it has been a while. I am studying Limits. I have a problem that I just can't seem to get. I know there has to be a simple trick to get this to be obvious, but that escapes me at this point. Let f: (0,inf)> R be such that Lim (x>inf) x*f(x) = L, prove that Lim (x>inf) g(x) = 0. any suggestions would be greatly appreciated. Thanks, David
