Den fullständiga lösningen ges av y = yh + yp = C1e2x + C2e-3x -. 5 löser p(D)y2 = g2 så kommer y = y1 +y2 att lösa p(D)y = g1 +g2; med andra ord: vi kan alltså ser ekvationen p(D)y(x) = h(x) i något intervall ]a, b[ som bestäms  Låt (a,b) vara en punkt som tillhör till definitionsmängden Df av en funktion f av två variabler. När man deriverar m.a.p. x tänker man på y som på en konstant.

d sinx, we begin with definition derivative: dx. d. cos(x The Schrödinger wave equation for a particle in a box. The particle in a box model lets us consider a simple version of the Schr ö dinger equation. Before we simplify, let's take another look at the full Hamiltonian for a particle-wave in three dimensions (see equation 2.2.2) and the simplest form of the Schrödinger equation (see equation 2.2.1).
