Hjortnes series for zeta(3) - PART II
We have previously showed that Today we will revisit this remarkable result proving it by a different method, namely, we will show that And compute this integral. First, lets find a series expansion for : Letting we obtain (1) Now recall (see here ) (2) Letting we obtain (3) Claim: Proof: Letting k=3 we obtain Let´s now calculate this integral Where we used (see here )
