TI-83 Sinusoidal Regression. If you have a TI-83 calculator, you can perform sinusoidal regression with the SinReg function in the STATS menu. The basic steps are below (or view the video on YouTube): Press STAT. Make sure EDIT is highlighted in the top row, then press ENTER. Type your x-values into L1, then type your y-values into L2.Computer spreadsheets, statistical software, and many calculators can quickly calculate the best-fit line and create the graphs. The calculations tend to be tedious if done by hand. Instructions to use the TI-83, TI-83+, and TI-84+ calculators to find the best-fit line and create a scatterplot are shown at the end of this section.

r A = 10m = 10b. To summarize, Exponential Regression. To obtain a best-fit exponential curve of the form. y = Ar^x. Find the regression line for the data (x, \log y). The desired coefficients A and r are then. \begin {align*} r &= 10^m\\ A &= 10^b \end {align*} where m and b are the slope and intercept of the regression line.4) Now tell the graphing calculator which lists to use for the regression, press [2nd] [L1] [,] [2nd] [L2]. 5) Press [ENTER] to perform the regression calculation. The TI-82 will display the form of the equation (y=ax+b) and then list the values for the two coefficients (a and b).The linear regression calculator generates the best-fitting equation and draws the linear regression line and the prediction interval. ….
