Unit Circle Chart - Trigonometric Values for Common Angles #2257631 (License: Personal Use)

This diagram displays the unit circle centered at the origin, marked with 16 critical angles from 0° to 360° (or 0 to 2π radians), each paired with its exact (x, y) coordinate representing (cos θ, sin θ). Labels include both degree and radian measures, along with simplified radical forms such as (√3/2, 1/2) for 60°. The axes are clearly labeled x and y, and quadrantal points like (1, 0), (0, 1), (-1, 0), and (0, -1) are explicitly shown.

Used in mathematics education-especially precalculus and trigonometry-to teach periodic functions, reference angles, and exact trigonometric values; commonly embedded in lesson pages, cheat sheets, or interactive learning tools where users seek visual reinforcement of angle-coordinate relationships.
