Sinusoidal Model Building Examples
"How to Video" on how to build a trigonometric model from data
Steps to Use Trigonometric Regression with Desmos
1) Enter Data into a table (this should be x1 y1 table if it is your first model)
2) type in function y=a*sin(bx+c)+d
3) This did not do anything
4) change = to tilde ~ SHIFT BLUE BUTTON (see images below for where tilde is)
5) change x to x1 (name of x data list (unless you have multiple x lists))
6) change y to y1 (name of y data list (unless you have multiple y lists))
DONE this should perform sinusoidal regression for you
tilde looks like ~
Tilde on keyboard is SHIFT `
(the button in blue) (the button to the left of 1) (button below esc)

Tilde on DESMOS keyboard is found on the QWERTY Keyboard page
1) Press ABC
GREEN ARROW pointing qwerty keyboard TAB
2) Press tilde button
RED Arrow pointing to tilde button
remember tilde looks like ~
