In mathematics, a cyclotomic polynomial is used to define the roots of unity based on angles that divide the circumference of a circle.

Examples

Over the rationals and, hence, contained in a single cyclotomic field.

Morphology

cyclotomic = cyclotomy (semi-transparent) = cyclotomy + ic

Formally derived from 'cyclotomy' with the adjective-forming suffix '-ic'; the relation is clear morphologically but the base is a technical mathematical term, so meaning is specialized.

Etymology

Cyclotomic comes from two Greek parts: cyclo- meaning 'circle', as in cycle, and -tomic meaning 'cut', the same root as atom which originally means 'uncut'. So cyclotomic is like 'circle-cutting' and helps remember why it means dividing a circle into equal parts in math.
