         This sentence should read, "This computed range is drastically different from its real age, which is about 4.5 billion years."

p. 94, Module 3.3, Project 4
         M(t) = 20 is an equilibrium solution and so cannot be the initial value for M.  Thus, assume the initial value for M, M0, is value slightly larger than 20, such as 20.00007. The second carrying capacity is M­­1 + M2  = 70 so that M2 is 50 for M­­1 = 20.

Notice that we get a "bilogistic" or "doubly logistic" model for P(t).

         Change the differential equation to dP/dt = 0.5(1 - P/1000)P with P0 = 20.  Alternatively, change the solution to P(t) = .

         On the second line of the text and on the last line in the shaded box, the formula for b should be as follows:
         b =
Thus, the answer to Quick Review Question 6 should change as indicated below.

b.      b =  = 6.01
c.      b sin(a) + µ = 6.01 sin(5.32) + 70 = 65.1
d.      b cos(a) + µ = 6.01 cos(5.32) + 70 = 73.4
