# Final state of a two-dimensional dynamical system

Calculus Level pending

A two-dimensional dynamical system is characterised by the following state equation:

$x(k+1) = A x(k)$

where

$x(k) = \begin{bmatrix} x_1(k) \\ x_2(k) \end{bmatrix}$

is the state vector, and matrix $$A$$ is given by

$A = \begin{bmatrix} 0.8 && 0.3 \\ 0.2 && 0.7 \end{bmatrix}$

Given that

$x(0) = \begin{bmatrix} 1 \\ 4 \end{bmatrix}$

Then what is,

$\lim_{k \to \infty} x(k) ?$
