I suppose that Sage knows Euler's formula because
sage: var('x')
x
sage: real_part(e^(I*x))
e^(-

I'm a bit confused by your question. If you mean k-th roots of unity in
the complex field CC then
sage: z =

I'm curious why you are so opposed to creating a number field.
Basically, there are three one-liners you can use:
