(English)
[J] J. Comput. Appl. Math. 75, No.1, 43-46 (1996). ISSN 0377-0427

Summary: Expressions for the polygamma function $\psi^{(k)}(x)$ for the arguments $x={1\over 4}$ and $x={3\over 4}$ are given in terms of Bernoulli numbers, Euler numbers, the Riemann zeta function for odd integer arguments, and the related series of reciprocal powers of integers $\beta(m)$.
