  • 16: 19.36 Methods of Computation
    When the differences are moderately small, the iteration is stopped, the elementary symmetric functions of certain differences are calculated, and a polynomial consisting of a fixed number of terms of the sum in (19.19.7) is evaluated. … If the iteration of (19.36.6) and (19.36.12) is stopped when c s < r t s ( M and T being approximated by a s and t s , and the infinite series being truncated), then the relative error in R F and R G is less than r if we neglect terms of order r 2 . …

    This result is refinable in two important ways. …
    18: 3.5 Quadrature
    Simpson’s rule can be regarded as a combination of two trapezoidal rules, one with step size h and one with step size h / 2 to refine the error term. … Further refinements are achieved by Romberg integration. …
