Pi expression

I had posted earlier that "Becoming Extroverted"(my blog) ideas result in sigma n!/(n^n). That is why this term occurs in faster pi expressions of Ramanujan and Chudnovsky brothers.
I am working on root 3 into sigma n!/(n^n).
The above results in 3.14 in just three iterations.
The equation has a scope and am further developing it. I am also trying to use "Becoming Extroverted" ideas in above to try and get further places of pi.
The screenshot of the last expression:
My final submission
1/pi to 10 places; the maximum my calculator can handle:
Divide 2.01........ by root 10. Divide again by 2.0031343434. You get 1 by pi. 
I believe the last

  1. I am trying to use 5! in root 3 into sigma n!/(n^n). There is some progress as further iterations gave 3 more places. But beyond that I am not sure.
    So, the result is 3 places of pi each for 2 iterations. And the end.
    I read in the internet that Chudnovsky brothers algorithm gives 4 places of pi for each iteration and it keeps going. So that is where the world is.

  2. Another thing is the continued fraction 2/(3+1/(5+2/(7+3/(9+4/(11+5 . . . .
    The above continued fraction is interesting and gives pi/5 (wait a second !!) to 99.79 % accuracy.
    I don't think it is perfect but then pi/5 for odd and even numbers do not exist for continued fractions. Maybe, some day someone will make it.

  3. 1/pi = 1/(3+1/(7-1/(11+1/(15-1/(19+1 . . .

    It is Madhava of Sangamagrama formula tried in continued fractions.

  4. It is a new beginning. Ages old formula of Madhava of Sangamagrama. Reapplied. And it seems correct.

  5. I work on intuitions in constants, especially after "measuring behaviour" resulted in a pi expressions.
    I thought about "Becoming Extroverted" also in pi lines. "Becoming Extroverted" was more of equal to.
    A person feels he is n!. Great combination. But the other is n^n. Too great an extrovert !!
    So I wondered as n!/n^n.

  6. So one thing is n!/(n^n) or n!/((n!)^n).
    Another thing is what can one do when somebody is b^n. My intuitions say one has to try a.n+b.
    These may be mad. But that's how I think.
    So, sigma {[dn!/(en^n)][a.n+c/b^n] is extroverted response equation. A pi formula !!
    And that is what is Ramanujan pi formulas are all about.
    You need to work-out or take guidance from Ramanujan materials to get a,b,c,d,e. And then you get pi.

  7. See Ramanujan Sato series in Wikipedia.
    I feel proud that I am involving in mathematics of British Raj times.

  8. Sigma ((n!)/((n!)^n))(comb(2n,n)) works a little.
    The above by 1.77 gives 3.14159 (six places ).

  9. I have put all the extroverted ideas together namely
    1. (n!)/((n!^n). Jealous
    2. comb(2n,n). Doubling. Measuring behaviour.
    3. (3^(0.5))/((5!)^n). Five fingers and phase difference.
    I made
    ((n!)(2n!)(3^(0.5)))/(((n!)^(n+2))(120^n)).
    The result is 2.0289717.
    Nothing great. Maybe multiplying and/or dividing by rational or irrational numbers may give results of pi or 1/pi.

  10. I tried some more
    1. (n!)/((n!)^n). Jealous.
    2. comb(2n,n). Doubling.
    3. (3^(0.5n)). Root terms.
    4. e^(11^0.5). Numerator of 5th term in the series of e^(11^0.5); 11 is heegner number.(121)
    5. 60n. Denominator of 1st term in the series for 1/11.(60 is 5 ×12)
    6. 1. An addition to say 60n is lagging 121^n.
    ((n!)(2n!)(3^(0.5n))(60n+1))/(((n!)^(n+2))(121^n))
    The result is 3.75876688697.
    No great shakes.

  11. I shall finish my poser.
    1. (n!)/((n!)^n)
    2. comb(2n,n)
    3. 144. 1/11 series.
    4. Root 2.
    5. 121. e ^(root 11)
    11 is heegner number.
    So sigma from 0 to 100 of
    ((n!)(2n!)(144n+(2^(0.5)))/(((n!)^(n+2))(121^n))
    results in 5.2418538001.
    Dividing above by 1.6685338865 is pi.
    1.6685338865 seems to be rational. Maybe 100/59.
    This finishes.

  12. Among the deceased mathematicians from India; I like
    Ramanujan
    Madhava of Sangamagrama
    Harishchandra
    Harishchandra was unlucky not to get Abel prize. He seemed great.
    I don't like much Aryabhata, Bhaskara. Very simple work have they done.
    Someone says in internet that they have discovered zero. What's this?
    I like Dr.Vashist Narayan Singh too. But he doesn't seem to be of complex numbers. Maybe something big.

  13. I have pasted the screenshot for the last but one comment.
    Now
    10/6(1+11/10000+20/1000000+33/100000000+60/10000000000) is very nearly 1.6685338865.
    It's great!! Yoo hoo !!
    Maybe a very quick pi expressions is here. One step away.
    This means jealousy, combination concepts are correct. Pi god says so.
    Initially it was like finding a needle in a haystack 50 square meters. Now it has been reduced to 1 square meter.
    And the result error is quite symmetric. Oooooooh wow!!

    ReplyDelete
  14. The result error is symmetrical but not possibly in mathematical terms.
    I think pi as a quick expressions is still far.

  15. I tried the following:
    ((n!)(2n!)(120n))/((n!^(n))(121^n))
    My logic was:
    1.(n!)/((n!)^n). Jealousy due to extrovertedness.
    2. comb(2n,n). Measuring behavior.
    3. (5!)n or 120n. Fingers of hand.
    4. 121^n. Heegner number squared.
    The above results divided by (root 10 into 2.00313434343434) is 1 by pi to 10 places. The maximum a calculator can display.
    Only checking needed is the recurring part in 2.0031343434 using large computers.
    I am pasting the screenshot above.

  16. I believe the last
    1. (n!)/((n!)^n). Jealous.
    2. comb(2n,n). Measuring behavior.
    3. 163. Heegner number.
    4. 10,5,2. Hands.

    8 places of 1/pi obtained.
