Talk:Cauchy Sequence Is Eventually Bounded Away From Zero

This proof looks fine, but the title is a bit imprecise: a Cauchy sequence is only eventually bounded away from zero if that is not its limit :-)

I would also formulate it more generally to state that it is bounded away from everything that is not its limit (in the proof, just replace 0 by any non-limit).

Something like "Cauchy Sequence Is Eventually Bounded Away From Non-Limit".


 * No point. The only reason for this is to allow the use of an eventually non-zero Cauchy sequence as the denominator in a quotient of such sequences. --prime mover (talk) 10:00, 4 October 2018 (EDT)


 * OK, so then "Cauchy Sequence with Nonzero Limit Is Eventually Bounded Away From Zero" -- but I agree it is getting a bit long. KarlFrei (talk) 11:20, 4 October 2018 (EDT)
