A fundamental domain for the ideal Z[ω]β = Zβ + Zωβ, acting by translations on the complex plane, is the 60°–120° rhombus with vertices 0, β, ωβ, β + ωβ. Any Eisenstein integer α lies inside one of the translates of this parallelogram, and the quotient κ is one of its vertices.

A complex number can also be defined by its geometric polar coordinates: the radius is called the absolute value of the complex number, while the angle from the positive real axis is called the argument of the complex number. The complex numbers of absolute value one form the unit circle.
One Shot is the ninth book in the Jack Reacher series written by Lee Child. The book title is based on "One shot, one kill," the military sniper's creed. The novel was adapted into the 2012 film Jack Reacher, starring Tom Cruise as the title character. This book is written in the third person.
Geometry of Complex Numbers is an undergraduate textbook on geometry, whose topics include circles, the complex plane, inversive geometry, and non-Euclidean geometry. It was written by Hans Schwerdtfeger , and originally published in 1962 as Volume 13 of the Mathematical Expositions series of the University of Toronto Press .
A split-complex number is an ordered pair of real numbers, written in the form z = x + j y {\displaystyle z=x+jy} where x and y are real numbers and the hyperbolic unit [ 1 ] j satisfies
