WebRomberg integration is an extrapolation technique which allows us to take a sequence approximate solutions to an integral and calculate a better approximation. This technique assumes that the function we are … Romberg's method is a Newton–Cotes formula– it evaluates the integrand at equally spaced points. If it is possible to evaluate the integrand at unequally spaced points, then other methods such as Gaussian quadratureand Clenshaw–Curtis quadratureare generally more accurate. See more In numerical analysis, Romberg's method is used to estimate the definite integral The method is named after Werner Romberg (1909–2003), who published the method in 1955. See more To estimate the area under a curve the trapezoid rule is applied first to one-piece, then two, then four, and so on.
