Modeling Using a Periodic Function (precalculus)

consider a situation in which you have a quantity that can be modeled by using a periodic function such as a sine or cosine.

Create a Word document that contains the following elements:
Explain the situation in detail.
Provide a formula for how the quantity depends on time.
Use the formula to address various questions related to the situation. For example, you might comment on the period and amplitude of the function.

Demonstrate and explain all the steps in the calculations you perform. Note that in this activity you need not work with actual data; nevertheless, you should come up with a realistic model for a real-world situation.
