This example demonstrates the trigonometric ratios of any angle. It involves key mathematical concepts such as trigonometric functions, angles, and segment lengths. Using GeoGebra commands like Intersect, Circle, Point, Segment, OrthogonalLine, Angle, and Slope, the construction of the trigonometric ratios of any angle is illustrated. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. Circle(A, B) → c
  3. Point(c) → C
  4. Segment(C, A) → a
  5. OrthogonalLine(C, xAxis) → b
  6. Intersect(b, xAxis) → D
  7. Segment(C, D) → d
  8. Segment(D, A) → e
  9. Segment(A, B) → f
  10. Angle(B, A, C) → θ
  11. Slope(a) → g

AI Drawing Prompt Reference

Draw the trigonometric ratios for any angle. Start by drawing a unit circle centered at the origin, then pick a point C on the circle and draw segments OC and OA. Construct a perpendicular line to OC through C, intersecting the x-axis at D. Draw segments CD and DA, and measure the angle AOC and the slope of OA.
