Task 1 (Spec 3.f). Consider the following fourth order linear constant coefficient initial value problem.
Look at it and enjoy its simplicity. Then solve it.
x" - 5x" + 4x = sin(t)
With initial conditions that x(0) = 0, x'(0) = 1, x" (0) = 0 and x"" (0) = 0.
Task 2 (Spec 3.g). A Lotke-Volterra system of differential equations models the populations of species in
a predator/prey system. That is Species A feeds off of resources in the environment while Species B feeds
on Species A. The basic form of the equations is:
Where a, ß, y> 0 and 0 <e < 1.
Find the equilibrium solutions in terms of a, B, y, e and classify using linearization the stability of each
equilibrium.
Modify the equations with a harvesting term h which is how many of Species y is harvested per year.
How large can h be while there is still a stable equilibrium with positive populations for both x and y?
Task 3 (Spec any). Go back and redo any one task you need regardless of the "last revision" date.
