Sinusoidal functions are a staple of Algebra 2 and Pre-Calculus but the modeling problems in the textbooks are always so dry. I can't stand any more weights on a spring or riders on a ferris wheel! I wanted to make a problem that would be more interesting than the classic textbook tropes and I also wanted students to experience data that could be modeled this way. Of course, data is never perfect so the data provided here can be modeled with sine or cosine but no model will completely exact.
