Arg Function

Description

The function \(Arg \) calculates the angle of a complex number.

A complex number can be identified by its coordinates (polar coordinates) on a complex plane.

If a line is drawn from the intersection of the x / y axes to the point representing the complex number, the angle of the complex number is equal to the angles of this line to the real axis (X-axis) of the coordinate system.

The absolute value (magnitude) is the distance from the point of origin to the point represented by the complex number.

You can determine the values of a complex number based on their polar coordinates by calling the FromPolar function.

Syntax

Arg (re + im)

Example

Arg(4+5i)= 51.3
