Engineering - IMARGUMENT Function

Description

The IMARGUMENT function returns the argument $\theta$(theta), an angle expressed in radians, such that −

$$x+yi=\left | x+yi \right |e^{i\theta }=\left | x+yi \right |(\cos\theta+\sin\theta)$$

Syntax

IMARGUMENT (inumber)

Arguments

Notes

• Use COMPLEX to convert real and imaginary coefficients into a complex number

• IMARGUMENT is calculated as follows −

  $$IMARGUMENT(z)=tan^{-1}\left ( \frac{y}{x} \right )=\theta$$

  Where

  $$\theta\epsilon (-\pi;\pi], and \: z= x+yi$$

Applicability

Excel 2007, Excel 2010, Excel 2013, Excel 2016
