A method for computing fo' f(t) dt, x = (0, 1) is outlined, where f(t) may have singularities at t = 0 and t = 1. The method depends on the approximation properties of Whittaker cardinal, or sinc function expansions; the general technique may be used for semi-infinite or infinite intervals in addition to (0, 1). Tables of numerical results are given.
