WebCyclotomic polynomials are an important type of polynomial that appears fre-quently throughout algebra. They are of particular importance because for any positive integer n, the irreducible factors of xn 1 over the rationals (and in-tegers) are cyclotomic polynomials. Furthermore, the minimal polynomial of
