Re: Series

Hi gAr;


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: Series

Your RHS is not the same your LHS. You forgot that k also changes.

Re: Series

If you expand the LHS, counting from n = 1 ... you exactly get the RHS. Please try it. The k's are changing in each sum but the first sum is divergent.

Hi bobbym

Yes,I see what you mean. I wrote 2k instead of 4k^2. I will need to fix that.
