MAKECOMPLEXIMINUS (Real,Imaginary)
- is the real part of the complex number.
- is the imaginary part of the complex number.
is the real part of the complex number.
is the imaginary part of the complex number.
Description
- MAKECOMPLEXIMINUS function converts the imaginary coefficient of a complex number into 'negative' coefficient.
- A complex number is a combination of a real and an imaginary number.
- A number which is positive or negative, rational or irrational or decimals are called real numbers.
- An Imaginary number is a number that when squring it gives a negative result.
- For e.g. . Because a negative times a negative is positive.
- A complex number is in the form , where and are real numbers and is the imaginary unit. Where
- To mention and , we must use the lower case only
- In a complex number real part is denoted by & imaginary part is denoted by .
- MAKECOMPLEXIMINUS returns the error value, when and are non-numeric.
- A Complex number whose real part is zero is said to be purely imaginary.
- A Complex number whose imaginary part is zero is a real number. In that cases we have to assign '0' for that part.
. Because a negative times a negative is positive.
, where 
and 
are real numbers and 
is the imaginary unit. Where 
, we must use the lower case only
real part is denoted by 
& imaginary part is denoted by 
.- =MAKECOMPLEXIMINUS (5,2) gives
- =MAKECOMPLEXIMINUS (5,2,["j"]) gives
ZOS
- The syntax is to calculate MAKECOMPLEXIMINUS in ZOS is
- is the real part.
- is the imaginary part.
is the real part.
is the imaginary part.Examples
- =MAKECOMPLEXIMINUS(4,5) = 4-i5
- =MAKECOMPLEXIMINUS(4,-5) = 4+i5
- =MAKECOMPLEXIMINUS(1,10,"j") = 1-j10
- =MAKECOMPLEXIMINUS(1,0) = 1+i0
- =MAKECOMPLEXIMINUS(1..3,5)
| Real | Imaginary | MAKECOMPLEXIMINUS |
|---|---|---|
| 1 | 5 | 1-5ⅈ |
| 2 | 5 | 2-5ⅈ |
| 3 | 5 | 3-5ⅈ |
