There are many results about the minimal polynomial of this algebraic number. Here we obtain the minimal polynomial of this number by means of the better known Chebycheff polynomials for odd q and give some of their properties.eninfo:eu-repo/semantics/closedAccessMathematicsHecke groupsRoots of unityMinimal polynomialsChebycheff polynomialsProceedings Paper0003022398000872-s2.0-818551869543533561389Mathematics, appliedHecke Groups; Modular Forms; Congruence Subgroups
