Simpson's rule - Wikipedia
Simpson's 1/3 rule, also simply called Simpson's rule, is a method for numerical integration proposed by Thomas Simpson. It is based upon a quadratic interpolation and is the composite Simpson's 1/3 rule evaluated for n = 2 {\displaystyle n=2} .
Simpson's Rule -- from Wolfram MathWorld
2024年12月6日 · Simpson's rule is a Newton-Cotes formula for approximating the integral of a function using quadratic polynomials (i.e., parabolic arcs instead of the straight line segments used in the trapezoidal rule).
Simpson’s Rule For Integration - Definition and Formula for 1/3 & 3/8 Rule
Simpson’s 1/3rd rule is an extension of the trapezoidal rule in which the integrand is approximated by a second-order polynomial. Simpson rule can be derived from the various way using Newton’s divided difference polynomial, Lagrange polynomial and the method of coefficients. Simpson’s 1/3 rule is defined by:

2.5: Numerical Integration - Midpoint, Trapezoid, Simpson's rule
2021年7月25日 · The most commonly used techniques for numerical integration are the midpoint rule, trapezoidal rule, and Simpson’s rule. The midpoint rule approximates the definite integral using rectangular regions whereas the trapezoidal rule approximates the definite integral using trapezoidal approximations.
Simpson’s Rule: Definition & Formula for 1/3 & 1/8 Examples
2023年5月4日 · Simpson’s rule is one of the Newton-Cotes formulas used for approximating the value of a definite integral. We first divide the function into n equal parts over its interval (a, b) and then approximate the function using fitting polynomial identities found by Lagrange interpolation.
