To estimate the area under a curve the trapezoid rule is applied first to one-piece, then two, then four, and so on. After trapezoid rule estimates are obtained, Richardson extrapolation is applied. • For the first iteration the two piece and one piece estimates are used in the formula (4 × (more accurate) − (less accurate))/3 The same formula is then us… WebRomberg Rule of Integration After reading this chapter, you should be able to: 1. derive the Romberg rule of integration, and 2. use the Romberg rule of integration to solve …
