Unit Circle Trig Generator v1.4

This interactive GeoGebra example dynamically generates sine, cosine, and related trigonometric values on the unit circle, visually linking an angle's measure to its function outputs. Core mathematical concepts include the unit circle definition of trigonometric functions, radian and degree measure, coordinates in the four quadrants, and the geometric interpretation of sine and cosine as segment lengths. The construction uses GeoGebra commands such as Intersect, Point, Angle, and Segment to place a movable point C on the circle, define angle α, and draw the sine and cosine segments along with auxiliary objects like Tangent, Sine, Cosine, and supporting lines. It is ideal for high school trigonometry lessons, pre-calculus review, and for teachers creating interactive demonstrations or students exploring trigonometric identities and periodicity.
