Length of Day Model Generation
I've made the toolbar available to you on this activity (if you use the desktop version, it's always available).
- Click and drag from A2 to B8, highlighting the data.
- From the dropdown menus, select "Two Variable Regression Analysis"
. This will open the function building tool. It uses statistics to build functions of various types that best fit bi-variate data. You might have to adjust the panes between graphics/spreadsheet/regression analysis to make it easier to navigate.
- Chose a "Regression Model" of type "Sin" from the drop down menu
- Just as earlier in this chapter, copy it to the graphics view by clicking the box with an arrow pointing up and right.

Remember: If you ever want to use your desktop version of geogebra, go to the absolute TOP RIGHT of the page, click the three dots, select "DETAILS" and you can download the .GGB file from the next page.
