1. The problem statement, all variables and given/known data Find liminf(xn) and limsup(xn) for xn = n(1-(-1)^n) 2. Relevant equations 3. The attempt at a solution I'm not really getting liminf and limsup, but stumbled through the method in my textbook and got liminf=0, limsup doesn't exist. Is that right? I don't think I did it right. If it's wrong, I can type out my working (I'd just prefer not to since it's pretty late).
