Re: Is this cool with you?

How did you get that?

Formula 19 - 20

But the important thing is why is it better?

Re: Is this cool with you?

Because it's alternating, of course. RRA is not working too fast, though. I cannot evaluate it quickly...

Re: Is this cool with you?

Alternating series can be hard to accelerate too! Heard of the converger?

Re: Is this cool with you?

Code:

acc[n_]:=Module[{d,b,c,s},
d=(3+Sqrt[8])^n;
d=(d+1/d)/2;
b=-1;
c=-d;
s=0;
Table[c=b-c;s=s+c*a[k];b=(k+n)(k-n) b/((k+1/2)(k+1)),{k,0,n-1}];
s/d]

Re: Is this cool with you?

I knew you were going to ask that.

First, it is for alternating series only. So enter

a[k_]:=1 / ( k + 1 ) then

N[acc[250],200]

what do you notice?

The converger always starts at 0.

That is true, but you asked what the series was.

Re: Is this cool with you?

Yes, but I meant in the form that the converger can use.

1) The series must be alternating.

2) It must start at 0.

The function acc has an input and a global variable a. These must be in the precise form required. That is why I did the transformation on the zeta series.

Re: Is this cool with you?

No, no, I got that it must start at 0. I was just saying that what I wrote and what you wrote are the same series.

So, you've got no idea how and why it works?

None at all. Did you see how it works on zeta(3)?
