The velocity of a particle at position r = (x, y), in two-dimensional Cartesian coordinates, is given by v = (αy,αx), where α ∈ R is a constant. What are the physical dimensions of the parameter α? Find the general form of r(t), the position of the particle, as a function of time t (hint: write v = (αy,αx) as a system of first order ODEs). What is the critical point and its nature in this system? Suppose at t = 0, r(0) = (2,0). By eliminating the variable t, find the nature of the particle’s trajectory and give a sketch of it.

5. Okay, time for some mathematics. We're going to focus on the interactions between the hares and their main predators, the lynx. The tool we need is differential equations (last seen when we talked about the S-I-R disease model). We will let H(t) be the density of hares at time t, and L(t) the density of lynx at time t. Our first assumption is that, if there are no lynx around, the hares grow exponentially. Hares lead to more hares and faster growth. This gives us the differential equation (trust me): HP = aH dt where a is a positive constant. Second we assume that, if there are no hares around, the lynx starve and thus their numbers decay exponentially. This gives us: TP = -bL dt
