Trigonometry, Unit Circle Dimensions as Sin/Cos of Angle Degrees

Level 1

This math topic focuses on trigonometry, specifically calculating the sine and cosine values of various degrees using the unit circle. The problems require determining the x or y dimensions (coordinates) for points at specific angles on the unit circle, such as 30°, 60°, 150°, 210°, and 240°. Each question provides options labeled 'a' and 'b', where learners must decide whether the value corresponds to sine or cosine of the given angle. This forms part of an advanced fundamentals course in trigonometry.
