SUMMARY

The discussion centers on proving the equality between two summation expressions involving the Euler-Mascheroni constant, denoted as \(\overline{\gamma}\). The left-hand side (LHS) is represented as \(N\,\overline{\gamma}\sum_{k=0}^{N-1}(-1)^k\frac{{N-1\choose k}}{(k+1)^2}\) and the right-hand side (RHS) as \(\overline{\gamma}\sum_{k=1}^N\frac{1}{k}\). The user suggests that induction may be a straightforward method for proving this equality, which has been derived from integral evaluations and binomial expansions. The discussion highlights the need for a systematic approach to transition from the LHS to the RHS.

PREREQUISITES
  • Understanding of summation notation and binomial coefficients
  • Familiarity with the Euler-Mascheroni constant, \(\overline{\gamma}\)

Hello,

How to prove this equality:

[tex]N\,\overline{\gamma}\sum_{k=0}^{N-1}(-1)^k\frac{{N-1\choose k}}{(k+1)^2}=\,\overline{\gamma}\sum_{k=1}^N\frac{1}{k}[/tex]?

Thanks in advance

It should be relatively easy to prove it by induction.

The result in the left hand side is my evaluation to an integral using the table of integrals and binomial expansion, and the result in the right hand side obtained from the authors, but I don't know how they did obtain it. The two results are equal and it is easy to proof that by substituting several values of N, but I am wondering if we can go from the LHS equation to the RHS systematically.

Regards
