  2. Complex number - Wikipedia

    en.wikipedia.org/wiki/Complex_number

    A complex number is an expression of the form a + bi, where a and b are real numbers, and i is an abstract symbol, the so-called imaginary unit, whose meaning will be explained further below. For example, 2 + 3i is a complex number. [3]

  3. Complex - Wikipedia

    en.wikipedia.org/wiki/Complex

    Complex commonly refers to: Complexity , the behaviour of a system whose components interact in multiple ways so possible interactions are difficult to describe Complex system , a system composed of many components which may interact with each other

  4. Complex (psychology) - Wikipedia

    en.wikipedia.org/wiki/Complex_(psychology)

    A complex is a structure in the unconscious that is objectified as an underlying theme—like a power or a status—by grouping clusters of emotions, memories, perceptions and wishes in response to a threat to the stability of the self.

    Complex analysis, traditionally known as the theory of functions of a complex variable, is the branch of mathematical analysis that investigates functions of complex ...

  6. Imaginary unit - Wikipedia

    en.wikipedia.org/wiki/Imaginary_unit

    The imaginary unit i in the complex plane: Real numbers are conventionally drawn on the horizontal axis, and imaginary numbers on the vertical axis.. The imaginary unit or unit imaginary number (i) is a mathematical constant that is a solution to the quadratic equation x 2 + 1 = 0.

  7. Imaginary number - Wikipedia

    en.wikipedia.org/wiki/Imaginary_number

    An illustration of the complex plane. The imaginary numbers are on the vertical coordinate axis. Although the Greek mathematician and engineer Heron of Alexandria is noted as the first to present a calculation involving the square root of a negative number, [6] [7] it was Rafael Bombelli who first set down the rules for multiplication of complex numbers in 1572.

  8. Napoleon complex - Wikipedia

    en.wikipedia.org/wiki/Napoleon_complex

    The Napoleon complex, also known as Napoleon syndrome and short-man syndrome, is a purported condition normally attributed to people of short stature, with overly aggressive or domineering social behavior. It implies that such behavior is to compensate for the subject's physical or social shortcomings.

  9. Complex conjugate - Wikipedia

    en.wikipedia.org/wiki/Complex_conjugate

    In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. That is, if a {\displaystyle a} and b {\displaystyle b} are real numbers, then the complex conjugate of a + b i {\displaystyle a+bi} is a − b i . {\displaystyle a-bi.}
