This discussion includes a derivation of the Euler–Lagrange equation, some exercises in electrodynamics, and an extended treatment of the perturbed Kepler problem. We also know that dx/dt = -100 when x = 2500 because the plane is initially 2.5 kilometers away from the radar station and has been converted to meters since all other quantities are in that unit. Ellipse: Conic Sections. Within mathematics, a differential equation refers to an equation that brings in association one or more functions and their derivatives. Differential equations began with the German mathematician Leibniz and the Swiss brother mathematicians Jacob and Johann Bernoulli and some others from 1680 on, not long after Newton’s fluxional equations in the 1670s.
