In this lab, students analyze GDP data from five fictional countries. To complete the activity, students: -- create scatterplots of their data using desmos.com/calculator (or other graphing utility) -- use their data sets to compute the parameters of underlying sinusoidal functions and use Desmos to compare their estimates to the data sets -- interpret the parameters of their equations in context by describing how the economies of each country compare and contrast to each other. -- are challenge
