Simpson's 3/8 rule, also called Simpson's second rule, is another method for numerical integration proposed by Thomas Simpson. It is based upon a cubic interpolation rather than a quadratic interpolation.
Simpson’s 3/8 or three-eight rule is given by: ∫ ab f (x) dx = 3h/8 [ (y 0 + y n) + 3 (y 1 + y 2 + y 4 + y 5 + …. + y n-1) + 2 (y 3 + y 6 + y 9 + ….. + y n-3)] This rule is more accurate than the standard method, as it uses one more functional value.

Learn how to derive and use Simpson's 3/8 rule to approximate integrals by a cubic polynomial function. See examples, formulas, error estimates and comparisons with Simpson's 1/3 rule.
10 paź 2024 · Simpson's rule is a Newton-Cotes formula for approximating the integral of a function f using quadratic polynomials (i.e., parabolic arcs instead of the straight line segments used in the trapezoidal rule). Simpson's rule can be derived by integrating a third-order Lagrange interpolating polynomial fit to the function at three equally spaced ...
