A polluted pool has an initial concentration of bacteria of 10* part/m2, while the
acceptable level is only 5 x 103 part/m³. The concentration of the bacteria will
reduce as fresh water enter the pool. The differential equation that governs the
concentration C of the pollutant as a function of time (in weeks) is given by:
dC
+ 0.05C = 0,
C(0) = 104
dt
(i)
Estimate the concentration of the pollutant after 15 weeks by taking a step
size of 1 week.
(ii)
Find the absolute error if the exact solution of Q3(a)(i) is
C(t) = 10*e-0.05t
