Trigonometry and measure of angles

This module expands on right-angled trigonometry to explore the geometry of the circle and the behavior of periodic functions. Students transition from degree-based calculations to the use of radians and unit circle definitions, enabling them to solve complex 2D problems involving bearings and non-right-angled triangles using the Sine and Cosine rules. By mastery of circular measure, students provide the necessary groundwork for advanced wave modeling and the study of periodic phenomena.
