Webb∫xi + 1 xi f(x)dx = hf(yi) + O(h3). Now if we substitute f(yi) with the expression derived explicitly in terms of f(xi) and f(xi + 1), we get ∫xi + 1 xi f(x)dx = h(f(xi + 1) + f(xi) 2 + O(h2)) + O(h3), which is equivalent to h(f(xi + 1) + f(xi) 2) + hO(h2) + O(h3) and therefore, ∫xi + 1 xi f(x)dx = h(f(xi + 1) + f(xi) 2) + O(h3).

Integration by Simpson's 1/3 rule can be represented as a weighted average with 2/3 of the value coming from integration by the trapezoidal rule with step h and 1/3 of the value coming from integration by the rectangle rule with step 2h. The accuracy is governed by the second (2h step) term. pat boone is known as
