Use the method of undetermined coefficients to:
obtain just a particular solution (the general solution can alwaysbe obtained easily by adding an arbitrary multiple of a solution of the associated homogeneous equation). In these exercises, the forcing function is an elementary sinusoidal function. If the forcing function is cos 5t, then a particular solution of the form A cos 5t will not work. However, a linear combination of cos 5t and sin 5t will work. Thus, the form for xp is A cos 5t + B sin 5t, where the constants A and B are determined by substituting the assumed form of the particular solution into the differential equation for x. In Exercises 47–52, the forcing function has severaldifferent terms. Use a form for xp consisting of the sum of the forms for each term.
