The nth roots of unity are, by definition, the roots of the polynomial x − 1, and are thus algebraic numbers. As this polynomial is not irreducible (except for n = 1), the primitive nth roots of unity are roots of an irreducible polynomial (over the integers) of lower degree, called the nth cyclotomic polynomial, and often denoted Φn. The degree of Φn is given by Euler's totient function, which counts (among other things) the number of primitive nth roots of unity. The roots of Φn are exac… WebJan 25, 2024 · FAQs on Cube Roots of Unity. Q.1. Explain cube roots of unity.
