IMAGINARY(ComplexNumber)

• $ComplexNumber$ is of the form $a+bi$.

Description

• This function gives the imaginary coefficient of a complex number.
• Complex number is a combination of real and an imaginary number.
• Imaginary number is a real number which is multiplied with the imaginary unit $i$, where $i={\sqrt {-1}}$.
• When imaginary number $bi$ is get adding to the real number $a$, then it forms a complex number.
• Also when we are squaring the imaginary number $bi$, it will give the negative real number ${-b}^{2}$.
• For eg $(5i)^{2}=-25$.
• We can use COMPLEX function to convert the real and imaginary coefficients to a complex number.
• A complex number is a imaginary number when the real part is zero.

ZOS Section

• The syntax is to calculate IMAGINARY in ZOS Section is $IMAGINARY(ComplexNumber)$.
  • $ComplexNumber$ is of the form $a+bi$.
• For e.g.,IMAGINARY("6-0.5i")

Imaginary

Examples

1. =IMAGINARY("2+3i")=3
2. =IMAGINARY("4-5i")=-5
3. =IMAGINARY("3j")=3
4. =IMAGINARY("7")=0

Equation	Real Part	Imaginary Part	Result(Imaginary)
=IMAGINARY("2+3i")	2	3i	3
=IMAGINARY("4-5i")	4	-5i	-5
=IMAGINARY("3j")	0	3j	3
=IMAGINARY("7")	7	0	0
