The population sizes of many animal species rise and fall over time. Suppose that the population size of a certain species can be modeled by the following function. p(t) = 2670 - 1270 cos 1.1t In this equation, pt represents the total population size, and t is the time in years.
Find the following. If necessary, round to the nearest hundredth.
Amplitude of p:
Frequency of p: cycles per year
Time for one full cycle of p : years
