1 Problems for the SIR lab 9 Name: Ryan Corley Section: 4 1. The effect of the parameter mu. (You can model this on section 5 the effect of the parameter lambda'.) Like Figure 4 plot the y(t) functions for mu = 1/10 1/14 and 1/18, on the same graph, (keep lambda at 0.001 and the same initial values for x(0), y(0) and z(0)). Complete a table like the table in Figure 5 except mu is in column one, instead of lambda. Discuss how the infection changes as mu changes, like section 5 discusses how the infection changes as lambda changes. [Three things, the graph, the table and the discussion.] 0 5 10 15 20 25 0 100 200 300 400 500 600 700 SIR: I for (lambda = .001) and decreasing mu=1/10 blue, 1/14 green, 1/18 red days people As the rate of recovery mu) increases from 1/18, 1/14, and finally to 1/10 the number of sick people decreases with a maximum around 8.5 days. Since there are fewer people who are infected because of a faster recovery then the number of people who are sick will be decreased. Before the peak at 8.5 days very few people
