CircleTrigonometryGeometric Construction
This example demonstrates the definition and properties of trigonometric functions through an interactive circle. Core math concepts include circle, radius, angle, and trigonometric functions (sine, cosine, tangent). It uses GeoGebra commands/objects like Intersect, Point, Segment, and Angle. Suitable for high school students to explore and understand the geometric relationship between trigonometric functions and circles.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → O
  2. Point(c) → P
  3. Segment(O, P) → a
  4. Intersect(c, xAxis, 2) → A
  5. Angle(A, O, P) → θ

AI Drawing Prompt Reference

Draw a coordinate system with an x-axis and y-axis. Take an arbitrary point on the positive x-axis and connect it to the origin to form a line segment. The angle between this line segment and the positive x-axis is labeled as θ, and the intersection point of the line segment with the x-axis is labeled as A. Then, draw a circle centered at the origin with the line segment as the radius. Mark the intersection point of the circle with the positive x-axis as P.
