Dioes the recurrence problem you gave me come from the integral?

How did you check the value of a[20] here?

In numerical work you either know the answer or you do not. You can answer that question for yourself.

Anything further to discuss on NA?

How do I chek the value of a_20?

Are you asking a program that has the following input and output?

Input: A set S, a natural r
Output: All possible subsets of S containing exactly r elements

It does not match with your answer

>>> n = 50
>>> a = 1241.0
>>> while n != 20:
...     n -= 1
...     a = ((1.0/n) - a)/8.0
... 
>>> a
0.005585251327875914

You'll have to wait. I have a computer issue.


Does the sequence of a converge as n goes towards infty?

#20 Re: Computer Math » Polynomial Root Finding » 2016-06-20 03:40:06

That is strange. I have never seen anything like this before

#21 Re: Computer Math » Polynomial Root Finding » 2016-06-20 03:36:57

And if I work all the way down to a[0], would it converge to log(9/8)?

#22 Re: Computer Math » Polynomial Root Finding » 2016-06-20 03:31:06

Something like 1 or 0 or Infinity?

#25 Re: Computer Math » Polynomial Root Finding » 2016-06-20 02:43:11

Oh I see!

What can we do about this?
