Argand Plane or Complex Plane is the plane formed by the complex numbers.
We all know that the pair of numbers can be represented on the plane, where is called abscissa and is called the ordinate.
Similar to the -axis and -axis in two-dimensional geometry, there are two axes in the Argand plane.
- The axis which is horizontal is called the real axis
- The axis which is vertical is called the imaginary axis
Definition
The plane having a complex number assigned to each of its point is called the complex plane or the Argand plane.
Polar Representation
The complex number which corresponds to the ordered pair is represented geometrically as the unique point in the -plane.
In the Fig 1.some complex number corresponding to the ordered pairs have been represented geometrically by the points mentioned in the below table.
