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

$\displaystyle z = 1e^(i(0 + 2*pi*k))$

$\displaystyle z = e^(i(2*pi*k))$

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!
