Unit Circle: Definition, Coordinates, Chart, Examples The unit circle is the circle of radius 1 centred at the origin, where every point on the rim has coordinates (cos θ, sin θ) for the angle θ measured from the positive x-axis This article covers the definition, the equation x² + y² = 1, why the coordinates are cosine and sine, the special angles in both degrees and radians, six worked examples, and the common mistakes
Unit Circle Calculator What is a unit circle? A unit circle is a circle with a radius of 1 (unit radius) In most cases, it is centered at the point (0, 0) (0,0), the origin of the coordinate system The unit circle is a really useful concept when learning trigonometry and angle conversion
