ARGAND DIAGRAM Meaning and
Definition
-
An Argand diagram, also known as a complex plane or Gaussian plane, is a graphical representation used to visualize complex numbers. It consists of a two-dimensional coordinate system in which the real part of a complex number is plotted on the horizontal axis while the imaginary part is plotted on the vertical axis.
The Argand diagram is named after Jean-Robert Argand, a Swiss mathematician, who introduced this method in 1806. It is widely used in mathematics and engineering to perform operations and analyze properties of complex numbers.
In an Argand diagram, each point represents a unique complex number. The position of a point on the diagram corresponds to the values of its real and imaginary parts. The origin of the diagram is represented by the complex number 0 + 0i or simply 0.
The magnitude or absolute value of a complex number is represented by the distance of its corresponding point from the origin, calculated using the Pythagorean theorem. The argument or phase of a complex number is represented by the angle, measured counterclockwise from the positive real axis, formed by the line connecting the origin and the point representing the complex number.
Argand diagrams provide a visual way to interpret addition, subtraction, multiplication, and division of complex numbers. They also help in understanding complex conjugates, complex roots of polynomials, and representing complex functions geometrically.

Etymology of ARGAND DIAGRAM
The term "argand diagram" is named after Jean-Robert Argand, a Swiss mathematician and physicist who introduced the concept of complex numbers in the late 18th century. Argand is credited with the invention of the diagram, which is a graphical representation of complex numbers. The word "argand" comes from Jean-Robert Argand's last name and is commonly used to describe this specific type of diagram.
