Find two sinusoidal equations that model real-world phenomena.

Write a description for each equation. For each example, address the following questions:

• What natural phenomenon does the equation model?
• What aspect of the natural phenomenon involves data that repeats after a given period of time?

Then use the equation to write a problem.
