[math-fun] harmonic series, Gosper 1974

Gosper 1974 found a nice sum which is equal to H(n) = SUM(k=1..n) 1/k but "converges faster" and also interpolates it for non-integer n. Question: Is there an analogous nice way to handle the "odd harmonic sum" 1/1 + 1/3 + 1/5 + ... + 1/(2n-1) ? -- Warren D.
