I'm completely math stupid so I'm just going to take your word for it. I literally read it a million times and I think I understand parts of it, but not fully.
for question 2, I'm assuming we fin the determinant of only "A". not "Av" because only "A" is 3x3 matrix =)

You're basically breaking the equations into the matrix. It confused me at first too, but when it clicks, you'll understand.
like, for example, you have ft = pat
The first column represents ft, the second mt, the third at.
So the first row for the first equation would show 0 for ft and mt, but p for at.
Does that make sense?

Yes, u will compute determinant and get polynomial, although it is already obvious since stochastic matrix will always have at least one eigenvalue and it is 1.

iFaer, yes that is starting to make sense. thank you =]
Differential, thank you for your help =)
I don't know anything at all about what a stochastic matrix is.
i got the following for the polynomial
p – λq + λ3 – λ2 + λ2p + λ2q

just put this polynomial into wolfram alpha and u will get root
p.s stochastic matrix = Markov Chain

o__o wolfram alpha can factor things with 3 variables?

I think u r able to calculate up to 4 roots using general formula but 5th is not possible(proven)

when I plug in 0.2 and 0.28 I get the following equation
λ3 –0.70λ2–0.28λ +0.02 = 0
which does not have roots o___o

@Ush.S: RELAX, BUD! You're going to be fine.  You have the whole of tomorrow to work on this, and Tuesday morning. So stressing now won't help, haha.

you put "-0.02", I put "+0.02"
isn't it supposed to be positive?
nevermind, i made a stupid mistake
