Imaginary number - Wikipedia
An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i 2 = −1. The square of an imaginary number bi is −b 2.For example, 5i is an imaginary number, and its square is −25.Zero is considered to be both real and imaginary. Originally coined in the 17th century as a derogatory term and regarded as ...

Imaginary Number -- from Wolfram MathWorld
Although Descartes originally used the term "imaginary number" to refer to what is today known as a complex number, in standard usage today, "imaginary number" means a complex number z that has zero real part (i.e., such that R[z]=0). For clarity, such numbers are perhaps best referred to as purely imaginary numbers. A (purely) imaginary number can be written as a real number multiplied by the ...

A Visual, Intuitive Guide to Imaginary Numbers ...
Imaginary numbers always confused me. Like understanding e, most explanations fell into one of two categories:. It’s a mathematical abstraction, and the equations work out. Deal with it. It’s used in advanced physics, trust us.

Imaginary Numbers - Friesian School
Imaginary Numbers. We have shown the symbol -a to be void of meaning, or rather self-contradictory and absurd.. Augustus De Morgan (1806-1871), Professor of Mathemtics, University College, London, 1831

Imaginary unit - Wikipedia
The imaginary unit or unit imaginary number (i) is a solution to the quadratic equation x 2 + 1 = 0.Although there is no real number with this property, i can be used to extend the real numbers to what are called complex numbers, using addition and multiplication.A simple example of the use of i in a complex number is 2 + 3i.. Imaginary numbers are an important mathematical concept, which ...

Complex Numbers: Introduction - Purplemath
Anyway, this new number was called "i", standing for "imaginary", because "everybody knew" that i wasn't "real".(That's why you couldn't take the square root of a negative number before: you only had "real" numbers; that is, numbers without the "i" in them.)The imaginary is defined to be:
