Real Analysis 17 | Cauchy Criterion [dark version]

[@malikbaud]

Hello i have a question about the proof. At the end of the proof we proved that (Sn) is convergent if and only if for all espilon ... for all n>=m>=N we have that the absolut value of Sn - Sm-1is less than epsilon how can we conclued that the serie is conv, i don't understant how we went from (Sn) converges to a serie is convergent if and only if the epsilon thing is true

Maybe you can explicitly write the difference Sn - Sm down. Then you see it.
