Complex Numbers (Part 2)

This video continues looking at dividing complex numbers by looking at the conjugate of a complex number. The instructor then uses the conjugate to rationalize the denominator of a rational expression with a complex number in the denominator. (Although, he doesn't use the terminology "to rationalize the denominator.") He ends the video by challenging the listener to graph the complex numbers in the complex plane and the results after addition, subtraction, multiplication, or division. Doing so, will help give learners a good visual representation of what each of those operations accomplishes.
