HiLanderin particular, equality would imply E_{m-1} = E_{n-1}
which is false by induction
TensHey.
noway-Does that really need induction then? Can't we just state what we have just said?
Tens"Use the formal Definition of a limit to prove that: Lim(x->2)(3x-4) = 2 You must find a suitable delta.
pyenosE_{m-1} != E_{n-1} since a set can't be an element of itself, as HiLander said
Steve|OfficeTens: So you need a delta in terms of epsilon.

TensThat circle w/ the squiggle on it is delta right?

Steve|OfficeEr, it's the one that looks like a d.

{{x -> 2}, {x -> (-2*ProductLog[Log[2]/2])/Log[2]}, {x -> (-2*ProductLog[-1, -Log[2]/2])/Log[2]}}
TensYeah it's delta.

Steve|Officer00723r0: Feel like /msging mbot with that?
r00723r0Steve|Office, sorry
noway-thats little delta
r00723r0didn't think it'd spam like that
TensSo Steve, I don't understand what I'm supposed to do.
Steve|OfficeTens: What is the definition of a limit?
in terms of epsilon and delta, that is.
You know what, never mind. landen is helping you on efnet. Don't ask your question on multiple networks at the same time.
Tensgah.
Sorry Steve.
