De Moivre's Theorem (Getting powers of complex numbers)
I will show where we get De Moivre's theorem and use it to get a large power of a complex number
required knowledge: Trigonometry, basic algebra, basis co-ordinate geometry, complex numbers
This course is suitable for any student doing a second level Maths course, for example leaving cert (Ireland), A levels (Britian) CIE 9709 (International)

I've started this youtube channel with the goal of covering an entire secondary level mathematics course, especially with a lot of the world in lock down this seemed like the prefect time to start this project.
The main reason I'm doing this is the hope that 1 or 2 people get something out of it, but also I know it will help me be a better teacher. So even if not many people watch it I'll be continuing to the end of the course.
