In mathematics, the nth cyclotomic polynomial, for any positive integer n, is the unique irreducible polynomial with integer coefficients that is a divisor of and is not a divisor of for any k < n. Its roots are all nth primitive roots of unity , where k runs over the positive integers not greater than n and coprime to n (and i is the imaginary unit). In other words, the nth cyclotomic polynomial is equal to It may also be defined as the monic polynomial with integer coefficients that is the minimal polynomial over the field of the rational numbers of any primitive nth-root of unity ( is an example of such a root). An important relation linking cyclotomic polynomials and primitive roots of unity is showing that x is a root of if and only if it is a d th primitive root of unity for some d that divides n.

Classifying a polynomial based on its degree and number of terms
👉 Learn how to classify polynomials. A polynomial is an expression of the sums/differences of two or more terms having different integer exponents of the same variable. A polynomial can be classified in two ways: by the number of terms and by its degree. A monomial is an expression of 1

Galois theory: Cyclotomic polynomials
This lecture is part of an online graduate course on Galois theory. We introduce cyclotomic polynomials, and use Frobenius automorphisms to show they are irreducible. We give two applications of them: we prove a special case of Dirichlet's theorem on primes in arithmetic progressions, and
