In this video we do a sinusoidal regression on the TI-Nspire. This is a skill you need to have for the AP Precalculus exam in May! (They'll probably just ask you in a multiple choice question to find the equation and then use it for something.) First we have to read an understand a problem, then use Lists & Spreadsheets to enter the data and run the regression. After that we use the regression equation to approximate a value and find an interval on which some condition is met.
This is from Unit 3, specifically 3.7.A.4.
