We begin with a quadrature formula based on the trapezoidal rule on intervals of length O(k1/2), with a slight modification near tn. More precisely, with v= [k-1/2] and k1 = vk, we put t¯l=lk1, and let ln be the largest integer with t¯lnωtn. For the interval [0, tn...

If the extreme points x = 0 and x = L of the interval are included in the set of nodes of a quadrature formula for approximately evaluating the line integral (such formulas are said to be Markov-type), then, for these classes, the best formula is the trapezoidal rule. Sharp error ...
