Complex Number Multiplication by denem

This example demonstrates the geometric interpretation of complex number multiplication, visually showing the result through vector rotation and scaling. Core math concepts include algebraic representation of complex numbers, vector rotation, magnitude, and argument operations. GeoGebra commands used in construction are: Distance, Intersect, Segment, Point, Angle. Suitable for high school mathematics teaching to help students understand the geometric intuition and the connection between algebraic operations and complex multiplication.
