In Chapter 6, we examine this and two other techniques for numeric integration. 51. 2 graphs the population versus time. The model states and the tab‘e and igure i‘‘ustrate that as the ”“”u‘ati“n increases, the gr“wth d“es, t““. The model gives an estimate of the population at various times. If the model is analytically correct, a simulation estimates the values for growth and population.

In general, the dt t = b dy derivative of y = s(t) with respect to t is written as sʹ(t), or , dt or dy/dt. or A function, such as y = s(t), can represent many things other than position. Moreover, we are not restricted to using symbols, such as s. For example, Q(t) might represent a quantity (mass) of radioactive carbon-14 at time t, and the instantaneous rate of change of Q with respect to t, Qʹ(t) = dQ/dt, is the instantaneous rate of decay. As another example, P(t) might symbolize a population at time t, so that Pʹ(t) = dP/ dt, is the rate of change of the population with respect to t.
