Suppose, you had to find the 5th roots of unity for 1, in polar form.
This is how far i'm getting.
You would say in the argand plane, 1 would make an angle of 0 to the horizontal and you would take r as being 1.
Then you would say
Apologises for the mess above, can't seem to figure out power brackets on this, it's all to the power of e ^
Then for each k, from 0 to 4, you would place into this formulae to get the 8 roots?
