## Practice: Modeling Events Using Periodic Functions

The following problems rely on the data contained in this spreadsheet. It has four tabs, and each problem will refer you to the appropriate tab. Note that this is real world data, not data generated for an “easy” math problem. Your model is NOT likely to hit all the data points perfectly. Sunrise 1 -…… Continue reading Practice: Modeling Events Using Periodic Functions
