The approximation can be justified by applying the procedure of the integral test for convergence to get .

A similar procedure will give you , , , and so on.

Is there a meaningful infinite set , such that

diverges ~

Like maybe let

But, for all I know, that could converge. (I know that if , then the series does converge.)

Actually, now that I think about it, that sum must converge, because

EDIT: Although, the above calculation seems to imply that if we let then diverges. - October 21st 2009, 08:58 PMchiph588@
diverges because one can show that given and prime , .

What's ? (And also, where does my proof of convergence go wrong?)

I'd say this equality is incorrect:

. This is because for a fixed (or ), the latter sum doesn't take into account how many times the (or ) appear in forming an arbitrary .
