Simpson's Rule. Simpson's Rule is a numerical method for approximating the definite integral of a function. It involves dividing the interval of integration into smaller subintervals and using quadratic approximations to calculate the area under the curve.
Also known as Simpson’s \(\textstyle\frac{1}{3}\) Rule is a numerical integration technique that improves upon the Trapezoidal Rule by utilizing the geometry of parabolic arcs. The number of partitions \(n\) must be even. \(\displaystyle S_n=\frac{b-a}{3n}\big( f(x_0)+4f(x_1)+2f(x_2)+\cdots+4f(x_{n-1})+2f(x_n) \big)\)
Simpson's rule is a method for approximating definite integrals of functions. It is usually (but not always) more accurate than approximations using Riemann sums or the trapezium rule, and is exact for linear and quadratic functions.
Simpson’s Rule is based on the fact that given any three points, you can find the equation of a quadratic through those points. For example, let’s say you had points (3, 12), (1, 5), and (5, 9). Starting with (3, 12) and using y = ax2 + bx + c, you could write: x y. 12 = a(3)2 + b(3) + c.
