Today we looked more closely at a specific type of a periodic function called sinusoidal functions.  This is the main topic of this unit.

Handouts:

• Waterwheel
• Sinusoidal functions

We began by graphing the height of a nail on a waterwheel such as the one on the side off this house:

Here's a more mathematical diagram:

As the wheel rotates, the height of the nail (located at x) changes.  We graphed this height as a function of the angle and it gave us this:

Get familiar with this shape because we will be graphing it a lot this unit!

Here are the notes form today:
