Example – cube roots of 1
In this series of videos I look at a method using De Moivre’s theorem to find the nth roots of 1 by using the following example:
Find the cube roots of 1 by using De Moivre’s theorem.
I also discuss some of the graphical properties associated with this on an Argand diagram.
Example – 4th roots of a complex number
In this video I look at a method to find the nth roots of a complex number by using De Moivre’s theorem
In this next example I find the 4th roots of a complex number.
