Please let me know if it is to hard to read and I will type out
and clarify the question. Thanks!
Suppose the roots of the auxiliary equation are as follows: mi = -1, m2 = 1, mz = 2 Then the general solution to the third order homogeneous Cauchy-Euler di equation is... y=Cje + + C et + Cze2u o y=Cje-7 + Cymet + C322eº y=C cos(-2) + C2 sin(c) + C3 cos (2x) y=C12-1 + C22 + Czar? y=Cixe 7 + Cyce" + Czæe
