Question

Suppose that a certain population satisfies the initial value problem

dy/dt=r(t)y−k,y(0)=y0,dy/dt=rty−k,y0=y0,

where the growth rate *r*(*t*) is given by *r*(*t*) = (1 + sin *t*)/5, and *k* represents the rate of predation.

a. Suppose that *k* = 1/5. Plot *y* versus *t* for several values of *y*_{0} between 1/2 and 1.

b.Estimate the critical initial population *y*_{c} below which the population will become extinct.
