Find liminf(xn) and limsup(xn) for xn = n(1-(-1)^n)
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).
