This example uses GeoGebra to demonstrate the concept of complex roots. It involves complex numbers, quadratic functions, and roots. Using GeoGebra commands such as Min, Line, Mirror, Roots, etc., it dynamically shows the properties of complex roots. Suitable for high school math education and learning.

GeoGebra Commands & Parameters

  1. Min(f, 2, 4) → A
  2. Line(A, xAxis) → g
  3. Mirror(f, A) → f_1
  4. Line(A, yAxis) → h
  5. Roots(f, -1, 7) → D, E
  6. CompleteSquare(f) → p
  7. Intersect(h, xAxis) → C
  8. Line(A, zAxis) → k
  9. Line(D, zAxis) → l
  10. Line(G, zAxis) → n
  11. Intersect(f_1, xAxis) → B, F
  12. Circle(h, G) → d
  13. Circle(h, B) → e
  14. Intersect(n, e) → H, I
  15. Segment(G, F) → j
  16. Segment(G, B) → q
  17. Line(I, xAxis) → r

  25. Plane((0, 0, 6), (0, 0, 0), (7, 0, 0)) → q_1
  26. Rotate(f_1, α, G, h) → f_2
  27. Plane((3, 2, 3), (3, 5, 6), (3, -2, -4)) → r_1
  28. Rotate(f, β, A, r_1) → f_3

AI Drawing Prompt Reference

Draw a quadratic function and its complex roots, showing the intersection points D and E with the x-axis, use reflection to get f_1 and show its intersection points B and F with the x-axis, also draw the complex roots z_1 and z_2.
