DEs

I need to answer this question. Can you help?


[1 0 1] [e^t ]
X' = [0 0 1] X + [0 ]
[0 0 2] [e^-t]

X and X' are vectors, obviously. I got


[t] [1] [0]
e^t(c1 [2] + c2 [0]) + c3 [1]
[1] [0] [0]

for the undriven case, which I'm fairly certain of, and


[te^t(1+K3) + e^t(K1) + .25e^-t]
[2e^t(K3) + e^-t + (K2 - 2K3) ]
[e^t(K3) - .5e^-t ]

for the driven case.

Take your best shot.
