This example demonstrates how to construct complex points on a parabola using tangents. Key mathematical concepts include parabolas, derivatives in calculus, and complex numbers. Using GeoGebra commands such as Polygon, Tangent, and Line, the construction process is dynamically illustrated. Suitable for high school mathematics education, particularly in coordinate geometry and complex numbers.

GeoGebra Commands & Parameters

  1. Polygon(P + (iplaneslicesize * {(1, 1), (-1, 1), (-1, -1), (1, -1)})) → iplaneslice
  2. Textfield(a) → InputBox1
  3. Textfield(b) → InputBox2
  4. Textfield(c) → InputBox3
  5. Intersect(d, f) → A,
  6. Tangent(A, d) → h,
  7. Line(B, h) → g
  8. Intersect(d, g) → C, D
  9. Line(P, h) → i
