This example demonstrates the geometric representation and variation patterns of generalized trigonometric ratios and their graphs. Key math concepts include trigonometric functions, vectors, angles, and coordinate systems. Construction highlights involve using GeoGebra commands like Circle, Point, Vector, and Angle to build the geometry, with sliders to dynamically display functions such as sin, cos, and tan. Suitable for high school and above mathematics learners to understand the geometric meaning and graph characteristics of trigonometric functions.

GeoGebra Commands & Parameters

  1. Circle((0, 0), 1) → c
  2. Point(c) → A
  3. Vector(B, A) → u
  4. Angle(C, B, A) → α

AI Drawing Prompt Reference

Draw a unit circle centered at the origin, then pick a point A on the circle, draw a vector u from the origin to A, and finally draw an angle starting from the positive x-axis and passing through A with angle α.
The prompt above was compiled from the original drawing commands and is for reference only.
