Difference equation formula

WebNow on the story of difference and differential equations. A first order difference equation equals a discrete dynamical system. Note that any difference equation can be converted to a system of first order difference equations (see higher order difference equations). Hence any difference equation equals a discrete dynamical system. WebDifferential equations are equations that involve derivatives. They can be used to model physical systems such as the motion of a particle or the flow of a fluid. Integrals can be …
