Talk:Alternating series test
From Wikipedia, the free encyclopedia
Is the Leibniz test a criterion, I think it isn`t --FHen 09:48, 3 February 2006 (UTC)
[edit] The counterexample.
The counterexample to the converse (the alternating harmonic series) has nothing to do with the alternating series test. Rather, it's a counterexample to the converse of the statement "any alternating series that converges absolutely converges," also true, but not the matter at hand. Since I can't come up with a counterexample, I'm removing it; if someone "in the know" could come up with a better one, that would be great. Twin Bird 17:28, 30 March 2006 (UTC)

- The only counterexamples I can think of are about finite series (an = 0 for n above some N). For n < N they can be anything, like nn :) --11:36, 25 June 2007 (UTC)

[edit] Wasn't very clear
I reworded it a little, in order to say more clearly that if the conditions hold then the series converges. LDH 19:01, 12 December 2006 (UTC)
