The last equation on the page should be:

\xi(t) = c_1 \left[ \begin{array}{c} 1 \\ 1 \end{array} \right] e^{3 t} 
+ c_2 \left[ \begin{array}{c} 1 \\ 0 \end{array} \right] e^{2 t} 
+  \left[ \begin{array}{c} -\frac{1}{50} \\ -\frac{3}{25} \end{array} \right] \cos 4 t 
+  \left[ \begin{array}{c} -\frac{1}{25} \\ \frac{4}{25} \end{array} \right] \sin 4 t

and the third to last equation on the page should be:

\xi_p(t) = \left[ \begin{array}{c} -\frac{1}{50} \\ -\frac{3}{25} \end{array} \right] \cos 4 t 
+  \left[ \begin{array}{c} -\frac{1}{25} \\ \frac{4}{25} \end{array} \right] \sin 4 t.
