The method of undetermined coefficients: only applied while p(x) and q(x) are constant, i.e., . Example: . Modification Rule: If a term in your choice for happens to be a solution of the homogeneous ODE, multiply your choice of by x (or by if this solution corresponds to a double root of the characteristic equation of the homogeneous ODE).

Method of Undetermined Coefficients: When g(t) is an exponential, sinusoid, or polynomial, make a guess for the particular solution that is the same exponential, sinusoids of the same frequency, or polynomial of the same degree, except with arbitrary coefficients that you determine by substituting your guess into the nonhomogeneous equation.

The general solution of the homogeneous equation can be obtained by the method discussed in the above sections. On the other hand, there are two methods to obtain the particular solution yp(x): Method of Undetermined Coefficients and Method of Variation of Parameters. Our main task in the following, is to discuss these two methods for finding ...
