This example demonstrates the process of multiplying complex numbers. It involves basic concepts of complex numbers, such as their representation and multiplication rules. Using GeoGebra commands like Segment, Angle, and SurdText, the geometric meaning of complex number multiplication is visually illustrated. Suitable for students in middle school and above to learn complex number operations.

GeoGebra Commands & Parameters

  1. Segment(O, z_{1}) → f
  2. Segment(O, z_{2}) → g
  3. Segment(O, z_{3}) → h
  4. Angle((1, 0), O, z_{1}) → α
  5. Angle((1, 0), O, z_{2}) → β
  6. Angle((1, 0), O, z_{3}) → γ
  7. SurdText(Length[f]) → f_{1}
  8. SurdText(Length[g]) → g_{1}
  9. SurdText(Length[h]) → h_{1}
  10. Segment((0, 0), z_{4}) → i
