Algebraic Numbers in the Complex Plane
An algebraic number is a root of a polynomial with rational coefficients. The image shows the roots of all monic polynomials of degree at most , whose non-leading coefficients are integers in the interval . Only the first quadrant is shown; the other quadrants are symmetrical to it.
