Because the function is a sine function, we know that it's periodic. Any idea as to what the period of this function represents? Well, let's think about it. The period of the function is basically the length of the cycle that's repeated over and over again. Therefore, in this context, it would represent how long one cycle of breeding patterns, or population patterns, of these rabbits is. Well, that would be interesting to know. Let's figure it out.
Why is the function periodic?
Because the number of degrees in a circle is 2 π, the angles x, x + 2 π, x + 4 π, …, x + n π, all intersect the circle at the same point. More specifically, their intersections with the circle all have the same y-coordinate which means they all have the same sine value. Because the value of x was arbitrary, the function is periodic with period 2 π.

Recall that sine passes through , while cosine passes through . this means that our function must be a sine function, because in order to be a cosien graph, we would need a horizontal translation as well.

Frequency is how often something happens per unit of time (per "1").
What is it called when frequency is per second?
When frequency is per second it is called "Hertz".
