Complex numbers form: a + bi where a and b are real numbers. The conjugate of a + bi is a - bi If you multiply a complex number by its conjugate, the product will be a real number, such as (a + bi)(a - bi) = a2 - (bi)2 = a2 - b2i2 = a2 - b2(-1) = a2 + b2
Yes, the difference between a complex number and its conjugate is a pure imaginary number. If we represent a complex number as ( z = a + bi ) (where ( a ) is the real part and ( b ) is the imaginary part), its conjugate is ( \overline{z} = a - bi ). The difference ( z - \overline{z} = (a + bi) - (a - bi) = 2bi ), which is purely imaginary since it has no real part.
It is a pure imaginary number.Since (a+bi)-(a-bi) = 2bi, it is a pure imaginary number (it has no real component).
Only if b = 0.
a complex number
The prefix Bi- represents the number 2.
Given a complex number z = a + bi, the conjugate z* = a - bi, so z + z*= a + bi + a - bi = 2*a. Note that a and b are both real numbers, and i is the imaginary unit: +sqrt(-1).
Yes. By definition, the complex conjugate of a+bi is a-bi and a+bi - (a - bi)= 2bi which is imaginary (or 0)
Complex numbers form: a + bi where a and b are real numbers. The conjugate of a + bi is a - bi If you multiply a complex number by its conjugate, the product will be a real number, such as (a + bi)(a - bi) = a2 - (bi)2 = a2 - b2i2 = a2 - b2(-1) = a2 + b2
A number of the form (a + bi) is a complex number.
"bi" means two. bi does not mean two because then why is bicycle there then 8(
if by "bi" you mean bye? then "sayonara" is the word.
"bi" means two. bi does not mean two because then why is bicycle there then 8(
You mean Bi-Sexual? No. He's straight.
Just because someone asks you if you're bi, it doesn't mean they are bi. It's possible, but they could just be curious or super nosy.
"Nichiyou bi" is a Japanese word and in English it means "Sunday"
"Suiyou bi" is a Japanese word and in English it means "Wednesday"
