Iterating a difference equationThis applet iterates a difference equation (also known as recurrence relation) and displays the resulting sequence both graphically and numerically.
Cobwebbing a difference equationThis worksheet performs iteration and produces cobweb diagrams for a first-order difference equation (AKA recurrence relation, discrete dynamical system).
Cobwebbing, linear approximation and stabilityThis applet shows a linear approximation to a non-linear difference equation close to an equilibrium, using cobwebbing. It can be used to investigate the accuracy of a linear approximation, or to motivate the linear stability criterion for equilibria of a first-order difference equation.
