Homework Statement


I uploaded the problem statement please see attachment for original problem. The problem number is 4.


Homework Equations





The Attempt at a Solution


For clarity I uploaded what I have done please see the attachment with my work on it. I am not sure if I am doing it right or not. If I am doing the problem correctly am I finished or should I do more? Just so you know I am doing the part from where it says suppose we are given a system of differential equations to the part where it says then finding the corresponding eigenvectors V.

You've got me confused! #4 on the page you give (there are NO "problems". This looks like a review sheet telling you what concepts you should review, not individual problems.) refers to y_1'= y_1+ 2y_2 and y_2'= 3y_1+ 2y_2 while your work sheet deals with y_1'= 5y_1+ 6y_2 and y_2'= 2y_1+ y_2.
 
I uploaded the incorrect thing sorry and I am confused as well but I can tell you I am not working the y1(prime) = y1+2y2 and y2(prime) = 3y1+2y2 part of it. I am trying to work out the general concepts listed. I am going to redo it and resubmit it.
 
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...
