FunctionTrigonometryGeometric Construction
This example demonstrates the graphs of sine and cosine functions. Key mathematical concepts include trigonometric functions, function graphs, and geometric constructions. Using GeoGebra commands such as Point, Circle, Segment, and Angle, the sine and cosine functions can be constructed. Suitable for high school mathematics education and learning.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Circle(A, 1) → c
  3. Segment((0, 0), (cos(theta), 0)) → cosine
  4. Segment((0, 0), (cos(theta), sin(theta))) → f
  5. Segment((0, 0), (1, 0)) → g
  6. Angle(g, f) → α
  7. Segment((theta, 0), (theta, sin(theta))) → i
  8. Segment((cos(theta), 0), (cos(theta), sin(theta))) → sine
  9. Segment((theta, 0), (theta, cos(theta))) → j
