Trapezoid Rule. Concept: Approximate f(x) as a linear function on the interval [a,b]. f(x) x a b f(x) x a b. • Requires function value at the midpoint. (can be a problem for tabular/discrete data). • Convenient form for tabular (discrete) data. • Doesn't require equally spaced data. • ?x = b-a. Simpson's 1/3 Rule. Simpson's 3/8 Rule.

2 Simpson's Rules. Aside from using the trapezoidal rule with finer segmentation, another way to improve the estimation accuracy is to use higher order polynomials. Figure 2: Illustration of (a) Simpson's 1/3 rule, and (b) Simpson's 3/8 rule. Simpson's 1/3 rule: Given function values at 3 points as (x0,f(x0)), (x1,f(x1)), and (x2
Simpson's 3/8 Rule. 0. Integration and algebraic manipulation of the Lagrange Polynomials: 0. Error: 0. Same order accuracy as Simpson' 1/3 rule – so 1/3 rule is usually desired. 0.

Derivation[edit]. Simpson's rule can be derived in various ways. Quadratic interpolation[edit]. One derivation replaces the integrand f ( x ) {displaystyle f(x)} f(x) by the quadratic polynomial (i.e. parabola) P ( x ) {displaystyle P(x)} P(x) which takes the same values as f ( x ) {displaystyle f(x)} f(x) at the end points a and b and
