Geometric Representation of Sine, Cosine, and Tangent on the Unit Circle

This applet demonstrates the geometric definitions of sine, cosine, and tangent using the unit circle. It shows how sine and cosine correspond to the y and x coordinates of a point on the circle, while tangent is a tangent segment. Users can dynamically observe changes in these ratios by manipulating the angle, providing an intuitive understanding of their relationship with the unit circle.
