About Unit Circle Interactive
Master trigonometry visually. Rotate the unit circle to see how sine, cosine, and tangent values change with the angle, providing a deep intuitive understanding of periodic functions.

Trigonometric Foundations
On a unit circle (radius = 1), the x-coordinate is the cosine of the angle and the y-coordinate is the sine. The tangent is the slope of the radius vector.
