OK, your opinion was the 2 questions should fall under 1 thread. How so? One had to do with the INERT vs ACTIVE for of the sum & integration operations. The other had to do with the ROUNDOFF error issue which you answered yourself, but I do not think it was addressed adequately. You did show convergence for higher number of terms in the series, but I still do not see how the error was so VASTLY huge for the 1 case over the other 3. So that question is still out there & has not been addressed by anyone else because you have already earmarked it as ANSWERED by you..
So if I have another question that can be remotely related to a previouls question you are going to delete it? Let me ask you this, if the question is 6 months old & has already been earmarked as ANSWERED then how would someone be provoked to read over the question? Any new twist will go UNREAD?
I find this unilateral moderator of posted questions a bit repressive. Are you the only one responsible for this?
