The question has a b and c in the first section. Please help me solve that.
The population model was described in Exercise 26 of Section 2.3. The population is given by P = Pe^(-kt), where P, c, and k > 0 are constants and t is the time. P(t) satisfies the equation P' = ln(P) - ln(P0).
a. Using t = 0 as 1960 and the data given in the table on page 103, approximate P.
b. Apply the Extrapolation method with h = 1 to the differential equation to approximate P(1990) and P(2010). Compare the approximations to the values of the Gompertz function and to the actual data.
