As an illustration of the difficulties that may arise in using the method of undetermined coefficients, consider X' = Form the complementary solution to the homogeneous equation. help (formulas) help (matrices) x.(t) = c1 + c2 Show that seeking a particular solution of the form x.(t) = e2"ā, where a = is a constant vector, does not work. In fact, if x, had this form, we would arrive at the following contradiction: az = help (numbers) and az = - Ip. help (numbers) Show that seeking a particular solution of the form xp(t) = te' a, where a = is a constant vector, does not work either. In fact, if x, had this form, we would arrive at the following contradiction: az = help (numbers) and aj = help (numbers) and az = help (numbers)
