Multiplying Complex Numbers - Concept

Concept Concept (1)

Sometimes when multiplying complex numbers, we have to do a lot of computation. Fortunately, when multiplying complex numbers in trigonometric form there is an easy formula we can use to simplify the process. To understand and fully take advantage of multiplying complex numbers, or dividing, we should be able to convert from rectangular to trigonometric form and from trigonometric to rectangular form.
