amplitude = 1270 beasties
cos 1.1 t = cos 2 pi f t = cos 2 pi t/T
so
2 pi f = 1.1
and
2 pi/T = 1.1
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.
In this equation, represents the total population size, and is the time in years.
p(t)=2670 - 1270 cos 1.1t

Amplitude of p: __
Frequency of p : __ cycles per year
Time for one full cycle of p : __ years
