We will explore the transformations of the basic sine function today.
- To start, open up this Geometer's Sketchpad file. Click on the "periodic motion" icon. Click on "walk the wheel" to observe how the sine curve is generated. Remember "Freddy the Frog"?
- Go back to the main menu and select "transformations of sine". Determine what happens for the different values of a, d, c and k. Look back at your investigation of transforming quadratics for some ideas.
- Record what happens when you modify each parameter (a, d, c, and k). Which features of the sine graph change?
- Go back to the main menu and select "the practice game". After getting a few correct in a row, move on to the "next challenge".
