Calculate the n-th stage of refinement of the Second Euler-Maclaurin summation rule which has the useful property of not evaluating the integrand at either of its endpoints but requires more function evaluations than the trapezoidal rule.
This rule can be used with a suitable change of variables to estimate improper integrals.
