I don't know if you have enough equations. See this example on SOS math: http://www.sosmath.com/diffeq/system/linear/eigenvalue/eigenvalue.html It seems like you know something about the addition of the two derivatives, but given a point in {a, b} space... you wouldn't have enough information to calculate the "velocity" of your solution's "point" in time t. That's just my guess. On 4/29/05, ames_kin at yahoo.com <ames_kin at yahoo.com> wrote: > a'[t] + b'[t]== -p1 a[t] - p2 b[t] > > where {a[0]== a0, b[0]== b0} > > is this solvable in Mathematica?
