Continued fraction for sqrt(e)
Hi all,

Can anyone point me towards a proof that the continued fraction expansion of sqrt(e) is [1,1,1,1,5,1,1,9,1,1,13...] (ie. a proof that the pattern continues)? I can find plenty for e itself but none for the square root.

Thanks!

Here you can find proof for continued fraction of $e^\frac{2}{k}$ :
