A dynamic interurban of people shows the following Markov Transition Matrix of residents to urban, suburban and rural areas:

__________Urban___Suburban____Rural
Urban ........... a................b...............y
suburban...... o..............q..............z
Rural ............ 1-a-o .........1-b-q ....... 1-y-z

A = 0.9
O = 0.05
B = 0.1
Q = 0.7
Y = 0.1
Z = 0.1

Solve the problem knowing that the vector answer today is
Uo ............ 10
(SUo) = (.... 40)
Ro ............ 50


What vector response to t = 2 vector and what is the answer in the long run. Remember that
Ut
(SUt) = Aλ1 ^ tX1 + Bλ2 ^ tX2 + Cλ3 ^ tX3
Rt

any bibliography suggestion?

Firs Question

If the serie


∑ Xn = (1/n²)
n=1

converge, then the serie |Xn| converge?

Second question

the serie

∑ X^n / [fat(n)] diverge?
n=1

where fat(n) = n(n-1)(n-2)...4.3.2.1

Its important know the value of X in X^n?

Let us take the first three non-zero terms of Maclaurin's expansion of
f(x)= Asen(ax) + Bcos(ax).
Determine for which values of a the equation f ' '(x) + f(x) = 0.
