Thread: nth roots of unity

Hello again,

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?

Thanks again!

The n nth roots of unity are; .
