Understanding the Unit Circle

Initially, students explore the unit circle as a fundamental tool in trigonometry, understanding the relationship between radians, angles, and coordinates on the circle. They learn how the unit circle helps define trigonometric functions. By Year 5, students use the unit circle to solve advanced problems in trigonometry, including transformations and wave functions.

Properties of the Unit Circle

Students explore the unit circle, starting with its basic properties and relationships between radians and degrees. They progress to understanding sine, cosine, and tangent values associated with the unit circle. By Year 5, they use the unit circle to solve complex trigonometric problems and explore advanced mathematical concepts.

Using the Unit Circle in Trigonometry

Students use the unit circle to understand the relationships between trigonometric functions and angles. They apply this knowledge to solve problems involving periodic phenomena, such as waves and oscillations. By Year 5, students use the unit circle to derive and solve trigonometric identities and equations, enhancing their ability to model and predict natural and technological behaviors.
