Pollution in a small loch

Using recurrence relations to look at pollution in a small loch

Argomento: Mathematics

Recurrence relations are set up to model pollution levels in a small loch. Dot plots are used to show the amount of pollution in the loch as the weeks pass. By looking at different initial values of pollution it can be shown that the limit of the sequence obtained in independent of the starting value for the recurrence relation. Students will see a good graphical representation of the amount of pollution in the loch with time.
