Hi guys,
The summation of i^2= n*(n+1)*(2n+1)/6
What is the summation od 1/i^2 ?
Thanks for your help.

I saw your other double post. I agree with the response there.
You have been given an honest and correct answer,
However, I will give you a different answer.
The infinite series (sum) is:
Therefore, for large values of N we can use as an approximation of
Let me tell you why I do not think so.
Consider a similar example,
And consider a Riemann integral over some positive closed interval on the function . If we try to calculate this sum directly through the definition of the Riemann integral we will probably not be able to because the true values is the logarithmic function which is transendental.
What in the world are you on about?
The harmonic series, , is a very slowly divergent series.
The series converges rather rapidly.
If fact for N=100 the estimate is correct in the first two decimal places.
For N=1000 the estimate is correct in the first four decimal places.
What is you point?
