24 de jun. de 2024 · Adrien-Marie Legendre. The Legendre equation is the second order differential equation with a real parameter λ. (1 − x2)y ″ − 2xy. + λy = 0, − 1 < x < 1. This equation has two regular singular points x = ±1 where the leading coefficient (1 − x ²) vanishes.
25 de jun. de 2024 · Based on the tables by Anton Felkel and Jurij Vega, Adrien-Marie Legendre conjectured in 1797 or 1798 that π(a) is approximated by the function a / (A log a + B), where A and B are unspecified constants. In the second edition of his book on number theory (1808) he then made a more precise conjecture, with A = 1 and B = −1.08366.
10 de jun. de 2024 · Adrien-Marie Legendre fut un mathématicien très actif, dans une période historique passionnante. Il a laissé son nom à plusieurs notions de mathématiques, polynômes de Legendre, symbole de Legendre, transformation de Legendre, par exemple.
Hace 4 días · In mathematics, the Legendre transformation (or Legendre transform ), first introduced by Adrien-Marie Legendre in 1787 when studying the minimal surface problem, [1] is an involutive transformation on real -valued functions that are convex on a real variable. Specifically, if a real-valued multivariable function is convex on one of its ...
26 de jun. de 2024 · In 1783, in a paper sent to the Académie, Adrien-Marie Legendre had introduced what are now known as associated Legendre functions. If two points in a plane have polar coordinates ( r , θ) and ( r ', θ'), where r ' ≥ r , then, by elementary manipulation, the reciprocal of the distance between the points, d , can be written as:
