The evolution of a population of Hippos, R(t), in hundreds, time in years, in an
African National Park is given by the equation,
dR
dt
(a) Solve the system exactly for R(t).
=
R(7 – R); R(0) = 3

(b) What happens as the time t → ∞o, i.e. what is the population a long time in the future?
(c) Write an Euler scheme and compute until the population levels off (using Excel, Matlab,
Octave, LibreCalc or similar). Do it twice, once with At = 0.1 and once with At = 0.05.
(d) Plot all of your solutions on the same set of axes and comment.
find
