Question
Recent studies seem to indicate the population of North America
porcupine (Erethizon dorsatum) varies sinusoidally with the solar (sunspot)
cycle due to its effects on Earth's ecosystems. Suppose the population of
these species in a certain locality is modeled by the function P(t) =
250cos (t) + 950 where P(t) represents the population of porcupines in year
t.
