,Green’s Function, point of the interval, we consider the equation in which the inhomogeneous term is the Dirac delta function, ., which is zero except at the point . within the interval. Its solution is called the Green’s function .. In considering the Green’s function for difference equations we follow closely the analysis presented for differential equations.

,Second Order Homogeneous and Inhomogeneous Equations, Sect. ., if one solution of the homogeneous equation is known then the method of reduction of order transforms a second order equation into a first order equation, which can then be solved in closed form. If the original second order equation is homogeneous then the transformed first order equation
