TrigonometryParametric EquationGeometric Construction
This applet demonstrates the formation of a cycloid, which is the curve traced by a point on the circumference of a circle as it rolls along a straight line. Key mathematical concepts include parametric equations and loci. It utilizes commands such as Circle, Intersect, Rotate, Angle, CurveCartesian, and Segment in GeoGebra. Suitable for high school mathematics education and learning parametric equations.

GeoGebra Commands & Parameters

  1. Circle(A, 1) → c
  2. Intersect(c, xAxis, 1) → B
  3. Rotate(B, (-a), A) → B'
  4. Angle(B', A, B) → α
  5. CurveCartesian(f(t), g(t), t, 0, (2 * π)) → b
  6. Segment(B', A) → h

AI Drawing Prompt Reference

Draw a cycloid, which is the path traced by a point on the circumference of a circle as it rolls along a straight line. Start by drawing a circle with radius 1 and center A. Find the intersection point B of the circle with the x-axis. Rotate B around A by angle a to get B'. Calculate the angle α between B', A, and B. Finally, use parametric equations to generate the cycloid b from t=0 to 2π, and draw a segment connecting B' and A.
