HELP!!!Questions on summing series?

The series doesn't have a 'nice' closed form expression, although there are some nice approximations and inequalities for the sum.

The sum you are describing is part of the harmonic series. The harmonic series itself diverges to infinity.

For the sum to n terms (written H_n):

ln (n + 1) < H_n < 1 + ln n

H_n ≈ ln n + γ

where γ is the Euler-Mascheroni constant, approximately 0.5772156649015... more information at http://mathworld.wolfram.com/Euler-MascheroniConst... or http://en.wikipedia.org/wiki/Euler%E2%80%93Mascher...

The sum to n terms does have an exact representation, although it involved special functions which are only really encountered in high level maths.

H_n = γ + ψ0(n + 1)

where ψ0 is the digamma function more information at http://mathworld.wolfram.com/DigammaFunction.html

1/1 +1/2+1/3+........+1/n

harmonic series

=ln(n)+.5772156649

The answer is 1n

yea its 1n

wat in the name of god r u talking about
