This example dynamically demonstrates the motion of a Ferris wheel, illustrating the relationship between angles, sine functions, and exponential functions. Core mathematical concepts include angle measurement, trigonometric function applications, properties of isosceles and equilateral triangles, and exponentiation. Construction highlights the use of GeoGebra commands such as Circle, Segment, Rotate, Angle, Line, OrthogonalLine, Intersect, and Distance. Suitable for high school mathematics education, exploring the integration of function models and geometric transformations.
