Hi

Very small question. Is $\displaystyle 1/n!$ a basic null sequence?

I know that $\displaystyle n^p/n!$ is when $\displaystyle p>0$ but not sure about the first one.

Just looking for some clarification

Thanks!!

Thanks - I wasn't totally sure!

One final one. Will $\displaystyle 1/(-1)^n$ be a null sequence? - Sep 14th 2008, 01:53 PMJhevon

Yeah. I asked this last night ( was feeling a bit tired and not with it). I did know it can't be a null sequence because of the $\displaystyle (-1)^n$ part, not sure what made me ask!(Sleepy)(Doh)

Thanks for the other bit though!!
