Nonhomogeneous Linear EquationsIn this section we learn how to solve second-order Nonhomogeneous Linear differential equa-tions with constant coefficients, that is, Equations of the formwhere , , and are constants and is a continuous function. The related homogeneousequationis called the complementary equationand plays an important role in the solution of theoriginal Nonhomogeneous equation (1).TheoremThe general solution of the Nonhomogeneous differential equation (1)can be written aswhere is a particular solution of Equation 1 and is the general solution of thecomplementary Equation we have to do is verify that if is any solution of Equation 1, then is asolution of the complementary Equation 2.
NONHOMOGENEOUS LINEAR EQUATIONS 5 We summarize the method of undetermined coefficients as follows: 1. If , where is a polynomial of degree , then try ,
