In collections Unit Circle Symmetries
This example demonstrates the relationship between the unit circle and the cosine function, focusing on y-axis symmetry. Key mathematical concepts include the unit circle, cosine function, function graphing, and symmetry. Construction involves GeoGebra commands such as Circle, Segment, and Angle. Suitable for middle or high school mathematics courses to understand basic trigonometric properties and graphing techniques.

GeoGebra Commands & Parameters

  1. Circle(O, 1) → c
  2. Segment(O, A) → a
  3. Segment(O, B) → b
  4. Angle(E, O, A) → α

AI Drawing Prompt Reference

Draw a unit circle with its center and radius marked. Show the cosine function graph and its relationship to the unit circle. Highlight the y-axis symmetry to make the graph clear and understandable.
