Finding critical points of a non-linear sysytem

Click For Summary
SUMMARY

The discussion focuses on finding the critical points of the non-linear system defined by the equations x1 = x2 + y2 - 2xy - 1 and y1 = y + x - 2. The user successfully identifies the critical points as (0.5, 1.5) and (1.5, 0.5) after substituting y = 2 - x into the first equation and solving for x. This method effectively reduces the complexity of the system, leading to the correct identification of critical points.

Homework Statement


I am trying to find the critical points of the system x1=x2+y2-2xy-1 and y1=y+x-2


Homework Equations


x1=x2+y2-2xy-1=0
y1=y+x-2=0

The Attempt at a Solution


I tried to solve for zero but I end up with multiple solutions way more then I should need any help answering would be helpful

So what I did was write y=2-x and substituted into x^2+y^2-2xy-1=0 to get an equation for x, I solved this and find x and then I used the answers to find y. the two critical points are (0.5,1.5) and (1.5,0.5)
 
thanks so much that really helps a lot
