**IMARGUMENT(Complexnumber)**

- is of the form .
- IMARGUMENT(), returns the argument theta, an angle expressed in radians

## Description

- This function gives the principal value of an argument of a complex-valued expression .
- i.e The angle from the positive axis to the line segment is called the Argument of a complex number.
- In this function angle value is in Radians.
- Here , Where Complexnumber in the form of . i.e & are the real numbers.
- imaginary unit ..
- An argument of the complex number is any real quantity such that = for some positive real number .
- Where and .
- The argument of a complex number is calculated by in Radians.
- To change the Radian value to Degree we can use DEGREES function or we can multiply the answer with .
- We can use COMPLEX function to convert real and imaginary number in to a complex number.

## ZOS

- The syntax is to calculate argument of a complex number in ZOS is .
- is of the form .

- For e.g.,IMARGUMENT("6.72+1.5i")

## Examples

- IMARGUMENT("3-2i") = -0.5880026035475675
- IMARGUMENT("5+6i") = 0.8760580505981934
- IMARGUMENT("2") = 0
- IMARGUMENT("4i") = 1.5707963267948966
- DEGREES(IMARGUMENT("2+2i")) = 45°
