Reflection: Connection to Prior Knowledge Complex Numbers and Trigonometry - Section 1: Bell work

This video is a quick look at how I develop rewriting complex numbers by using prior tools. After working with a specific problem. I have students general and write how z=a+bi is converted to trigonometric form. Students work in groups for a few minutes (2-3) to develop their process. I then as different groups to discuss what has to be done. We formalize the rule and students are able to put this in their notes.
