Unit Overview:
This unit builds on students’ previous work with functions, and on their work with trigonometric ratios and circles in geometry. Students now use the coordinate plane to extend trigonometry to model periodic phenomena.
Instructional Segment I: The Unit Circle, Radians, and Degrees
Instructional Segment 2: Graphing Trigonometric Functions
Instructional Segment 3: Proving Trigonometric Identities
Enduring Understanding:
