Exercise 6.2.1 For each system of ODE in (a)-(g), do the following:
Formulate the system as x = Ax, by explicitly writing out the matrix A.
Find the eigenvalues and eigenvectors of A and use them to write out a general solution
using (6.17).
. If any eigenvalues for A are complex, write out a real-valued general solution.
• Use either form of the general solution to obtain the given initial data.
