Some formulas for the Bernoulli and Euler polynomials at rational arguments

In a recent paper [5], the classical Bernoulli and Euler polynomials were e xpressed as finite sums involving the Hurwitz zeta function. The object of this sequel is first to give several remarkably shorter proofs of each of t hese summation formulas. Various generalizations and analogues, which are r elevant to the present investigation, are also considered.
