Let us say i keep splitting the limits i.e from 1 to 2 then 2 to 3 and so on from n to n+1 . I use limit n -> infinity.

The value would be like this 1 - (log 2 - log1 ) + 1/2 - ( log 3 - log 2) + ... 1/n - ( log (n+1) - log n ) = γ.

Firstly sigma 1/n should have been approx to log ( n+1) rather than log(n) .

In such a case the error would be .5 .

So why do we approx to me log(n) and what is the specialty of the constant .
