Why the conjugation only change the sign of the imaginary part?

when you square a negative number you also get a positive result (because a negative times a negative gives a positive)

What is conjugation of 7-2i?
The conjugate of a complex number can be found by multiplying the imaginary part by -1, then adding the "real" part back. (-2i) * -1 = 2i, so the conjugation is 7+2i
Why conjugation only change imaginary part?
Let a and b be real numbers, then (a + bi)(a - bi) (complex conjugates) = a2 - b2i2 by definition i2 = -1 = a2 + b2 (the sum of two real numbers is also a real number)
Are imaginary and complex numbers the same?
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.
How can you tell which part of a complex number is the real part and which is the imaginary part?
The imaginary part is expressed as a product of i(square root of negative one), typically following a plus sign, so that the complex number has the form a + bi, with "a" the real part and "bi" the imaginary part.
Can a number be both complex and imaginary?
A complex number has a real part and a (purely) imaginary part, So imaginary numbers are a subset of complex numbers. But the converse is not true. A real number is also a member of the complex domain but it is not an imaginary number.

Is every complex nberan imaginary number?
No. A complex number consists of a real part and a imaginary part. If the real part equals zero, there is only the imaginary left and you could therefor argue that it is an imaginary number (or else it would still be a complex number -with a real part=0)
How do you change the complex decimals to fractions?
You convert the real part and the imaginary parts separately.
If a verb belongs to third conjugation what will the second principal part end in?
The second principal part of a verb in the third conjugation will end in -Δre.
What family is third conjugation in latin?
All the verbs that end in -o in the first principal part and -ere in the second principal part. Note: some people count verbs that end in -io in the first principal part and -ere in the second principal part as third conjugation. However, others place it in a different conjugation called 'third -io conjugation.'
Are imaginary and complex numbers the same?
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.
What Latin principle part tells the conjugation?
Verb
Is Every complex number is a pure imaginary number?
No. All Complex Numbers are of the form a + bi where a and b are Real Numbers and i is the square root of -1. So only ones where a = 0 are pure Imaginary Numbers.
What part of speech imaginary?
The word "imaginary" can function as both an adjective and a noun. As an adjective, it describes something that exists only in the imagination. As a noun, "imaginary" refers to the mental process of creating images or ideas that do not actually exist.
How do you write a pseudocode for additing two complex number?
Real part of the result = real part of first number + real part of second number Imaginary part of the result = imaginary part of first number + imaginary part of second number
What part of speech is the word imaginary?
The word "imaginary" is an adjective.
