Legendre equation hamugeš-e Legendre Fr.: équation de Legendre The → differential equation of the form: d/dx(1 - x^{2})dy/dx) + n(n + 1)y = 0. The general solution of the Legendre equation is given by y = c_{1}P_{n}(x) + c_{2}Q_{n}(x), where P_{n}(x) are Legendre polynomials and Q_{n}(x) are called Legendre functions of the second kind. Named after Adrien-Marie Legendre (1752-1833), a French mathematician who made important contributions to statistics, number theory, abstract algebra, and mathematical analysis; → equation. |
Legendre transformation tarâdiseš-e Legendre Fr.: transformation de Legendre A mathematical operation that transforms one function into another. Two differentiable functions f and g are said to be Legendre transforms of each other if their first derivatives are inverse functions of each other: df(x)/dx = (dg(x)/dx)^{-1}. The functions f and g are said to be related by a Legendre transformation. |
