IMCONJUGATE(ComplexNumber)

• $ComplexNumber$ is of the form a+bi.
  • IMCONJUGATE(), returns the complex conjugate of a complex number

Description

• This function gives the conjugate of a complex number.
• Let the complex number be $z=a+bi$, then: $IMCONJUGATE(a+bi)={\bar {z}}=a-bi$ and it is denoted by ${\bar {z}}$ or $z^{*}$.
• So complex number and complex conjugate both also having same real number and imaginary number with

the equal magnitude and opposite sign of a imaginary number.

• The properties of a Complex Conjugate are:

1. $z={\bar {z}}$ if imaginary number is '0' and ${\bar {\bar {z}}}=z$
2. $|{\bar {z}}|=|z|$ and $|z|^{2}=z.{\bar {z}}={\bar {z}}.z$
3. $Realpart(a)={\frac {z+{\bar {z}}}{2}}$
4. $Imaginarypart(b)={\frac {z-{\bar {z}}}{2i}}$.

• We can use COMPLEX function to convert the real and imaginary coefficients to a complex number.

ZOS

• The Syntax is to calculate IMCONJUGATE in ZOS is $IMCONJUGATE(Complexnumber)$.
  • $ComplexNumber$ is of the form a+bi.
• For e.g.,IMCONJUGATE("-10+8.25i")
