IMCONJUGATE(z)

• where $z$ is the complex number.

Description

• This function gives the conjugate of a complex number.
• The complex number $z=a+bi$, then $IMCONJUGATE(a+bi)=z(bar)=a-bi$ 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.Also

1. $z={\bar {z}}$ if imaginary number is '0' and $z={\bar {\bar {z}}}=z$
2. $|{\bar {z}}|=|z|$ and $|z|^{2}=z.{\bar {z}}={\bar {z}}.z$
3. Real part (a)=z+z(bar)/2
4. Imaginary part(b)=z-z(bar)/2i.We can use COMPLEX function to convert the real and imginary coefficients to a complex number.

Examples

=IMCONJUGATE("3+4i")=3+-4i =IMCONJUGATE("6-7i")=6+7i =IMCONJUGATE("2")=2+0i =IMCONJUGATE("8j")=0+-8j =IMCONJUGATE("5+0i")=5+0i
