Real Analysis 18 | Leibniz Criterion [dark version]

6:31 There is a small mistake on the board: as you say, (s_(2l+1)) is monotonically increasing, but then you write (mon. decreasing) instead

Oh, sometimes I make small mistakes. Always be careful :)

[@awesomecraftstudio]

Isn't this true for every converging sequence with alternating sign? Every positive converging sequence with limit 0 must be monotonically decreasing after some point, or not?

[@brightsideofmaths]

Yes, we need a sequence that converges to zero :)
