need help!!
prove that Lim n→ ∞ 1 / √(n+1) = 0? and please remember that this is not calculus but real An.
thanks
you need to show that $\displaystyle \left| \frac 1{\sqrt{n + 1}} - 0 \right|< \epsilon$ for $\displaystyle \epsilon > 0$ and $\displaystyle n$ "suitably" large
what does n have to be larger than for $\displaystyle \frac 1{\sqrt{n + 1}}$ to be less than $\displaystyle \epsilon$?
of course you would phrase all this to conform to the sequence definition of the limit given in your text...
