If s = 1 / (1 / 1980 + 1 / 1981 +... + 1 / 2000 + 1 / 2001), then the integral part of S is? Solving with inequality

If s = 1 / (1 / 1980 + 1 / 1981 +... + 1 / 2000 + 1 / 2001), then the integral part of S is? Solving with inequality


1 / (A-A) + 1 / (a + a) = 2A / (a-178; - a-178;) > 2 / A, and when a-178;



S = 1 / (1 / 1980 + 1 / 1981 + 1 / 1982 +. + 1 / 2001)?
The last integral is 1 / 2001


1/1980+1/1981+1/1982+.+1/2001>22*1/2001
1/1980+1/1981+1/1982+.+1/2001
