Home > Imaginary part

In mathematics, the imaginary part of a complex number z is the second element of the ordered pair of real numbers representing z, i.e. if then the imaginary part of is .

In terms of the complex conjugate , the imaginary part of z is equal to

The imaginary part of is denoted or . It is not holomorphic.

If a complex number is written as , then the imaginary part is . (See Euler's formula.)

Imaginary numberIn mathematics, an imaginary number (or purely imaginary number is a complex number whose square is negative or zero. The term was coined by Rene Descartes in 1637 in his La Geometrie and was meant to be derogatory: obviously, such numbers were thought noImaginary unitIn mathematics, the imaginary unit i allows the real number system R to be extended to the complex number system C . Its precise definition is dependent upon the particular method of extension. The primary motivation for this extension is the fact that noImaginary countryAn imaginary country or fantasy country is often important in mail art, as it issues its own artistamps.
