@aeiklmkv Are you saying that you don't know how to program in Mathematica? If so, why are you trying to solve this problem in Mathematica? What is your best programming language?

comment How does RootOfUnityQ work?
Ok, suppose that this is the definition of RootOfUnityQ. The purpose of my question was to be able to verify Mathematica's answer for myself. So my question now becoems this: how does Mathematica compute ArcTan[Sqrt[1/2 (1+Sqrt[5])]]/\[Pi]\[Element]Rationals?

@R.M I am not looking for (numerically) approximate answers. I want to know with certainty.
