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

Level 1

This topic practices advanced trigonometry skills involving the unit circle. It focuses on calculating the sine and cosine values for various angles, specifically how these functions determine the X and Y dimensions (coordinates) of points on the unit circle. The problems provide specific angle measures such as 240°, 300°, 150°, and 225°, and ask for the corresponding sine or cosine value, reflecting an understanding of how trigonometric ratios correspond to coordinates on the unit circle. Each question is centered around interpreting and calculating these trigonometric values for given angle degrees.
