Clarifications:
Essential Understandings
Concrete:
- Use tools to manipulate the midline of a sine or cosine graph (e.g., calculator, graphing software, coordinate grid, transparency).
- Understand that the midline is the horizontal center of the graph and it is often the x axis.
- Understand that adding or subtracting a constant to the trigonometric function will shift the function and its midline up or down. For example: y=sin(x)+2 shifts the midline and the graph up 2 units.

Cluster:
Model periodic phenomena with trigonometric functions. (Algebra 2 - Additional Cluster) : Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters. |
