A bifurcation occurs where the number of equilibrium solutions changes as the parameter varies. As 8 increases, the number of equilibrium solutions changes from two to one and eventually there are none. 4. Solve the equation 0 = yd – 2y + Bfor y in terris of B. Describe how the number of solutions depends on B. 5. Sketch the bifurcation diagram, which shows the graph of y versus 8. It is traditional to show stable equilibria with solid lines...

2) Difference equations of the form xn+1=ƒ(xn) are a somewhat old-fashioned approach. A more modern approach is to use difference equations of the form Δx=ƒ(xn) where Δx = xn+1- xn. Explore the difference equation Δx=ƒ=r xn (1-xn). a) Algebraically determine the equilibrium and its stability as functions of r. b) Construct a simple bifurcation by hand by graphing the equilibria as a function of r. Represent a stable equilibrium with a solid graph and an unstable equilibrium with a dashed or...
