This example demonstrates the concept of trigonometric ratios, including sine, cosine, and tangent. Using GeoGebra commands such as Intersect, Segment, and OrthogonalLine, it helps students understand the basic properties of trigonometric functions. Suitable for middle and high school mathematics education.

GeoGebra Commands & Parameters

Intersect(xAxis, yAxis) → A
Segment(A, P) → r
OrthogonalLine(P, xAxis) → b
Intersect(b, xAxis) → C
Segment(A, C) → χ
Segment(C, P) → γ
Circle(A, P) → e
Angle(P, C, A) → α
Angle(C, A, P) → θ
Intersect(r, χ) → D
