TI-92 -- Sequences -- Cycles


The help screens below may be useful for this module.

The screen below illustrates how the TI-92 can be used to look for 2-cycles of a dynamical system

p(n) = f(p(n - 1))

by looking for solutions of the equation

f(f(p)) = p

In this particular example the equation has four solutions. The first two show immediately but the second two don't fit on the screen. We pressed ENTER a second time and then used the cursor pad to show the second two solutions.

The TI-92 can also help locate 2-cycles roughly by graphing the functions

f(p)
f(f(p))
p

as shown in the screen below.
