Equation solving — In mathematics, to solve an equation is to find what values (numbers, functions, sets, etc.) fulfill a condition stated in the form of an equation (two expressions related by equality). These expressions contain one or more unknowns, which are… … Wikipedia
Équation de Kepler — En astronomie, l équation de Kepler est une formule liant l excentricité e et l anomalie excentrique E à l anomalie moyenne M. L importance de cette équation est qu elle permet de passer des paramètres dynamiques du mouvement d un astre (l… … Wikipédia en Français
Point spread function — The point spread function (PSF) describes the response of an imaging system to a point source or point object. A related but more general term for the PSF is a system s impulse response. The PSF in many contexts can be thought of as the extended… … Wikipedia
