Hace 2 días · This exact rule is known as the Gauss–Legendre quadrature rule. The quadrature rule will only be an accurate approximation to the integral above if f (x) is well-approximated by a polynomial of degree 2n − 1 or less on [−1, 1]. The Gauss–Legendre quadrature rule is not typically used for integrable functions with endpoint ...

Hace 5 días · The Legendre symbol is a function that encodes the information about whether a number is a quadratic residue modulo an odd prime. It is used in the law of quadratic reciprocity to simplify notation.
Hace 5 días · The quadratic reciprocity theorem was conjectured by Euler and Legendre and first proved by Gauss, [1] who referred to it as the "fundamental theorem" in his Disquisitiones Arithmeticae and his papers, writing. The fundamental theorem must certainly be regarded as one of the most elegant of its type.
29 de jun. de 2024 · In mathematics, the Legendre transformation (or Legendre transform), first introduced by Adrien-Marie Legendre in 1787 when studying the minimal surface problem, is an involutive transformation on real-valued functions that are convex on a real variable.
Hace 3 días · The ordinary generating function for Legendre polynomials is \begin{equation} \label{EqLege1.1} G(x,t) = \frac{1}{\sqrt{1 -2xt + t^2}} = \sum_{n\ge 0} P_n (x)\, t^n , \end{equation} where P n ( x is the Legendre polynomial of degree n .
28 de jun. de 2024 · The standard design principle for quadrature formulas is that they should be. exact for integrands of a given class, such as polynomials of a fixed degree. We show how this principle fails to predict the actual behavior in four cases: Newton-Cotes, Clenshaw-Curtis, Gauss-Legendre, and Gauss-Hermite quadrature.
