The following applet shows how to multiply and add complex numbers (vectors in the plane).  See instructions below. Hit help twice to go to a lesson on complex numbers.


For multiplication, add the angles and multiply the lengths to get the product. Hit the button C=A*B twice to turn on and off the arc illustration of angle addition. The illustration works best when both factors are in the first quadrants. Hit the button C=A+B to again and again to alternate between illustrations of the head-to-tail method and the component method for vector addition. Now experiment or play. The help button will take you away from this web directory to another explanation of complex numbers.

Free Help:  Submit a question by email if you cannot find what you need in site pages for high school or college maths courses - answers will be added to site content. Private Instruction (not free) available with audio, whiteboards or video available on a per lesson or stand-by (if I am available) basis.
