Suppose a population function P(t) satisfies the following
differential equation. P is measured
in millions and t is
in years.
dP/dt = P(P − 10),
(a) Sketch a slope field.
(b) Identify the equilibrium solutions (constant solutions) and
classify them as stable, unstable, or semi-stable
equilibrium.
(c) Sketch a solution that satisfies the initial
condition P(0)= 6. [Show asymptote, if there is one, and
indicate the exact P value of the inflection point.]
(d) Write a definite integral for computing the time that it takes
for an initial population of 6 (millions) to decline to 0.5
(million.) [Hint: Separate the variables. Think
of t as a function of P.]
