Section 3.9 We call your attention especially to Example 8, on the free vibration of a two-mass system. We return to that problem in Section 11.3 and study it there in tenns of the matrix eigenvalue problem. It is an important problem, and you may wish to give it added emphasis by discussing it in class, both for Section 3.9 and Section 11.3, and even comparing the two lines of approach to the solution. 1

NOTE: Before continuing, note that the different cases defined in Theorem 4.3.1 depend on whether the roots of the indicial equation are equal, differ by a number not an integer, or differ by an integer. Since we will not be solving all parts of this lengthy problem, let us at least give the indicial roots for all parts of the problem, to assist you in choosing which parts to assign.
