Iterating the Cosine Function
by Mike Martin

This page allows you to investigate the dynamics of the cosine function. The difference equation is:

λ is the parameter in the equation. x1 is the initial value for the sequence -- the first term. This page will generate graphs associated to this sequence and produce the last M terms of a sequence that is T terms long. Enter the value of the parameters below, then press Evaluate.



λ =

T =

M =

x1 =


The graphs are given by:


Numerical values for the last M terms of a sequence that is T terms long are given by:
