Learning Objective
I can graph sine and cosine functions and identify their key features.
- 1
The midline of a periodic function is a horizontal line where half of the function is above it and half is below it.
- 2
The amplitude of a periodic function is how far the function varies from the midline, either above or below.
- 3
The period of a periodic function is the change in x needed to complete one cycle, returning to the same point and slope.
