Hello,

I had an assignment that required me to solve for the roots of unity for various equations of the form z^n-1=0. Then , I was asked to represent the roots of unity for each equation on an argand diagram in the form of a regular polygon.

I did all of that , but I have a critical question ,

is there a relation ship between the power n and the length of the polygon side?

I mean , for the euqation Z^3 - 1 = 0 for example, is there a formula relating the power to the lenght of one side of the polygon ?

Thanks.
