Ecology students studying various wildlife populations would like to modify the deer population model that we studied in In-Class Activity 5.B in order to model other populations. All of their Part A: A wolf population where R(0) = 80 and the difference between the minimum and maximum models have the form population is 30. P(1) - Asin ( 30' ) + c C = for some values of A and C. Suppose they identify a population of coyotes where that P(0) = 55 and the maximum population is go. Find the correct values for A and C to model this population. Part B: A rabbit population where R(0) = 110 and the minimum population is 100.
