Big Concept: Trigonometric Functions
Topic: Unit Circle
Bloom's Taxonomy: understand
Learning Goal: Explain sine and cosine using the unit circle and connect them to coordinate values and their graphs
Key Learning Points: sine/cosine as coordinates, radians, connection to graphs
Note: Assess integration of representations and whether misconceptions (e.g., sine/cosine as memorized values rather than coordinates) are addressed
