(a) Consider the linear system of three firstorder
Chapter , Problem 15RP(choose chapter or problem)
(a) Consider the linear system \(\mathbf{X}^{\prime}=\mathbf{A} \mathbf{X}\) of three first order differential equations, where the coefficien matrix is
\(\mathbf{A}=\left(\begin{array}{rrr}
5 & 3 & 3 \\
3 & 5 & 3 \\
-5 & -5 & -3
\end{array}\right)
\)
and \(\lambda=2\) is known to be an eigenvalue of multiplicity two. Find two different solutions of the system corresponding to this eigenvalue without using a special formula (such as (12) of Section 8.2).
(b) Use the procedure of part (a) to solve
\(\mathbf{X}^{\prime}=\left(\begin{array}{lll}
1 & 1 & 1 \\
1 & 1 & 1 \\
1 & 1 & 1
\end{array}\right) \mathbf{X}
\)
