Dave Posted August 6, 2005 Share Posted August 6, 2005 I don't know what the n'th term test is, but I suspect it's got something to do with the ratio lemma. To show a series is convergent, you need to show that the series of partial sums [math]s_n = \sum_{k=1}^n a_k[/math] is convergent. There are a series of results that can help you with this, though (i.e. comparison test, ratio lemma, etc). Link to comment Share on other sites More sharing options...
Crash Posted August 6, 2005 Author Share Posted August 6, 2005 Could you suggest any good sites or books? Cheers Link to comment Share on other sites More sharing options...
Dave Posted August 6, 2005 Share Posted August 6, 2005 The one book I would suggest is Guide to Analysis, M. Hart. It's rather good and has lots of examples to get you started. Link to comment Share on other sites More sharing options...
