Unit Circle Explained: All 16 Angles, Coordinates Trig Values . . . What Is the Unit Circle? The unit circle is a circle with a radius of exactly 1 unit, centered at the origin (0, 0) on the coordinate plane Its equation is x² + y² = 1, which comes directly from the Pythagorean theorem applied to a right triangle drawn inside the circle
Unit Circle - GeeksforGeeks A unit circle is a circle with radius 1 unit, centered usually at the origin (0, 0) on the coordinate plane Equation is x² + y² = 1; every point (x, y) on it is exactly 1 unit away from the center
