This example demonstrates the changes of a sphere under different parameters, involving geometric transformations and dynamic display. Using the Circle and Sequence commands, the size and position of the sphere can be dynamically changed. Suitable for high school and above students or teachers for geometric construction and dynamic demonstration.

GeoGebra Commands & Parameters

  1. Circle(A, r) → c
  2. Sequence(Sequence[If[Distance[(i, j), A] < r, Point[Segment[(i, j), ClosestPoint[c, (i, j)]], (a * Distance[A, (i, j)] / r)], (i, j)], i, 1, n], j, 1, m) → liste3
