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

This math topic focuses on understanding trigonometric functions using the unit circle, specifically calculating the sine and cosine values of given angles in radians. The main skills practiced include identifying the x and y dimensions (cosine and sine values, respectively) of points on the unit circle at various specific angles such as 2π/3, 4π/3, π/4, 7π/4, π/6, and 5π/3. The problems help solidify one's understanding of the unit circle in the context of trigonometry fundamentals at an advanced level.
