    Default Fun with DEs

    Solve the following, anyone?
    <pre>
    [1 0 1] [e^t ]
    X' = [0 0 2] X + [0 ]
    [0 0 1] [e^-t]
    </pre>
    X and X' are vectors, obviously. I got
    <pre>
    [t] [1] [0]
    e^t(c1 [2] + c2 [0]) + c3 [1]
    [1] [0] [0]
    </pre>
    for the undriven case, which I'm fairly certain of, and
    <pre>
    [te^t(1+K3) + e^t(K1) + .25e^-t]
    [2e^t(K3) + e^-t + (K2 - 2K3) ]
    [e^t(K3) - .5e^-t ]
    </pre>
    for the driven case.

    Take your best shot; I guess I'm just looking to make sure I'm right.
