Fixed Points of two differential equations

Click For Summary
SUMMARY

The discussion focuses on determining the fixed points of the system of differential equations given by dx/dt = x(β-x-ay) and dy/dt = y(-1+ax-y). The key method discussed involves dividing the first equation by the second to obtain the relationship dx/dy = [x(β-x-ay)]/[y(-1+ax-y)]. This approach allows for the analysis of the fixed points by setting both equations to zero and solving for the variables x and y in terms of the parameters β and a.

Homework Statement


Determine all fixed points of:
dx/dt = x(β-x-ay)
dy/dt = y(-1+ax-y)

β and a are parameters.

I get what to do when there is just one differential equation, but not two.

Divide dx/dt = x(β-x-ay) by dy/dt = y(-1+ax-y) and you will get
(dx/dt)/(dy/dt) = [x(β-x-ay)]/[y(-1+ax-y)] = dx/dy
