WebJul 25, 2024 · First, recall that the area of a trapezoid with a height of h and bases of length b1 and b2 is given by Area = 1 2h(b1 + b2). We see that the first trapezoid has a height Δx and parallel bases of length f(x0) and f(x1). Thus, the area of the first trapezoid in Figure 2.5.2 is. 1 2Δx (f(x0) + f(x1)).

Romberg's method examples

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.
