Complex Plane
The complex plane is a term for the set of all complex numbers. Just as all real numbers can be imagined as lying on a line, all complex numbers can be thought of as points in a plane.
Complex plane is a high school-level concept that would be first encountered in a pre-calculus course covering complex numbers. It is listed in the California State Standards for Algebra II.
Prerequisites
Cartesian Coordinates: | Cartesian coordinates are the usual coordinate system, originally described by Descartes, in which points are specified as distances to a set of perpendicular axes. Also called rectangular coordinates. |
Complex Number: | A complex number is a number consisting of a real part and an imaginary part. A complex number is an element of the complex plane. |
Real Number: | A real number is a number corresponding to a point on the real number line. |
