Roots of Unity Lesson (Part 2 of 3): Worked Example

This is a lesson I recently had to teach for an assessment on my Masters of Teaching program. I was pretty happy with how it turned out, so thought I'd share it more widely in case any students need to brush up on their roots of unity. Enjoy!
Apologies in advance about the poor video quality. I recorded on my phone and foolishly used the front camera instead of the back. Doh!
