What Determines the Real and Imaginary Parts of a Complex Number?

[Sampad Saha]

we know Complex number is consists of a real & imaginary number so if a+ib is a complex number which one is real part, imaginary part, real number and imaginary number?
I think "a" real and "ib" imaginary part...pleasez help me if Iam wrong ...

 

[Svein]

I think "a" real and "ib" imaginary part

As long as you have a and b real, a + ib is the standard representation of a complex number (and, of course, i is the imaginary unit with i² = -1).

 

[jfizzix]

the real and imaginary parts of a complex number are like $x$ and $y$ components of a vector.

The real part is the number of "ones" you have, and the imaginary part is the number if "i's" you have

Given a complex number $a+bi$
$a$is the real part
and
$b$ is the imaginary part

You have amount $a$ of "ones", and amount $b$ of "i's"

 

[Mark44]

Given a complex number $a+bi$
$a$is the real part
and
$b$ is the imaginary part

It's a little confusing at first, but the real part and the so-called imaginary part b, are real numbers.

Just to add that, to be precise, Complex numbers can also be represented in polar form.
