Hi. Suppose I have two conditionally convergent series $\sum \limits_{n=1}^{\infty} s_n$ and $\sum \limits_{n=1}^{\infty} t_n$.
According to http://mathworld.wolfram.com/ConvergentSeries.html the series $\sum \limits_{n=1}^{\infty} s_n + t_n$ will then also be convergent. Does this hold for conditionally convergent series? (I just want to be sure :D) Also, if it holds, can one say anything about the value of $\sum \limits_{n=1}^{\infty} s_n + t_n$?
Thanks

Okay... if you say so. But why? I thought I could post any math-related stuff here xD – iolo Nov 1 2011 at 10:45
hi @lolo, reading the faq might help you answer the "why?" – S. Sra Nov 1 2011 at 10:53
@Suvrit argh. Dreadfully sorry... Can I close this question somehow? – iolo Nov 1 2011 at 11:03
Not to worry, it will be closed very soon. – Gerry Myerson Nov 1 2011 at 11:16
