Complex Multiplication

Drag "A" and "B" and observe the complex product A*B.

Sorry, the GeoGebra Applet could not be started. Please make sure that Java 1.4.2 (or later) is installed and active in your browser (Click here to install Java now)

What happens if "A" has length < 1? length = 1? length = 2?

Use the applet to investigate division.

Think about what happens when you square a complex number.
