1-2-3 POPULATION GROWTH GRAPH

I have enclosed a WK1 file (Lotus worksheet) as a candidate for inclusion in your free software, or for any use you might want to make of it. It is named CHAOS.WK1, and it provides the opportunity to observe how a graph changes when one or two variables change in the equation defining the graph.

The equation was originally used to model population development in a limited environment, where the next generation's population is determined by this generation's population, times a specified growth rate, times the distance the present population is from complete saturation of the environment.
