Problem # 3: A vector y R() F(t)]T describes the populations of some rabbits R(t) and foxes F(t). The populations obey the system of differential equations given by y' - Ay where 398 6030 27 409 The rabbit population begins at 85500. If we want the rabbit population to grow as a simple exponential of the form R)Roe4 with no other terms, how many foxes are needed at time 0? Note that the eigenvalues of A are i -4 and...

The following problem can be interpreted as describing the interaction of two species with populations x and y. (A computer algebra system is recommended.) dx dy =y(3.5-y-s). (b) Find the critical points. (Order your answers from smallest to largest x, then from smallest to largest y.) G1 (x, ) 0,0 C2 (x, y)-(10. C3 (x, y) (11,0 (c) For each critical point find the corresponding linear system. (Let u =x-xo and v = y-yo where (Xo, yo) is the critical...

(1 point) This problem is concerned with solving an initial boundary value problem for the heat equation: (0,t)-0, t0 u,o)- in the form, ie where the term involving cy may be missing. Here y is the eigenfunction for Ay- 0 so if zero is not an eigenvalue then this term will be zero First find the eigenvalues and orthonormal eigenfunctions for n1.iA. Pa(x). For n 0 there may or may not be an eigenpair. Give all these as a comma...

1. A population of monkeys on an island in the Amazon river is preyed upon by margays (a type of small cat). Within this population the largest monkeys are too big for the margays to catch and the smallest monkeys are too agile for the margays to catch. Thus the mid-size monkeys have the lowest fitness. Over time this population could potentially split into two populations and two separate species of large and small monkeys. What type of speciation would occur...

This time, you are asked to analyze the time dependent behavior of two masses (m, and m.) connected by a massless spring. You may assume that the spring is linear, has a spring constant k and a free length of L. That is if the spring is stretched to length L' > Lit exerts a compressive force of magnitude (L' L). However, if compressed, ie., L' <Lit exerts an expansion force of magnitude (L-1). In Newtonian Mechanics, motion of the...
