Interactive Unit Circle by Jim Nordman

This example demonstrates the unit circle and its relationship with angles and trigonometric values. Key math concepts include the unit circle, angle conversion between degrees and radians, and trigonometric functions (sine, cosine, tangent, etc.). Construction highlights involve commands like Segment, with objects such as circle c, angle Θ, origin Origin, point B, line Line, point A, sine Sine, point C, cosine Cosine, point E, point D, point a, tangent Tangent, point F, point G, cotangent Cotangent, point b, secant Secant, cosecant Cosecant, radian Rad, and text1. Suitable for high school mathematics education to understand trigonometric definitions and unit circle applications.
