5. Use the matrix exponential to find
the general solution for the system
of D.E.'s , where
A fundamental matrix solution is .
The matrix exponential is .
The solution to the D. E. with initial conditions , is .
We are done.
Aside. We compare the above work, with the construction of using Mathematica's subroutine MatrixExp.
