Homework Statement



Find the equilibrium state of the dynamical system

x1(t+1)=−05x1(t)−02x2(t)−1
x1(t+1)=26x1(t)+07x2(t)+1

the 1's and 2's after the x's are actually subscripts

I have no idea where to start with this. We did equilibrium systems in class but I've never seen the information represented this way and I have no idea where to start.
I'm more just looking for an explanation on how to read the equations.
Thanks in advance

hi cris623! :smile:

(try using the X2 icon just above the Reply box :wink:)

hint: in equilibrium, x1(t+1) will be the same as x1(t), won't it? :wink:
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
