Imaginary number - Wikipedia
An imaginary number is the product of a real number and the imaginary unit i, [note 1] which is defined by its property i2 = −1. [1][2] The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. The number zero is considered to be both real and imaginary. [3] Originally coined in the 17th century by René Descartes [4] as a derogatory term ...

An imaginary number, when squared, gives a negative result. Let's try squaring some numbers to see if we can get a negative result:
Complex number - Wikipedia
A complex number z can be visually represented as a pair of numbers (a, b) forming a position vector (blue) or a point (red) on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the "imaginary unit", that satisfies i2 = −1. In mathematics, a complex number is an element of a number system that extends the real numbers ...

What is an imaginary number anyway? Imaginary numbers are based on the mathematical number . From this 1 fact, we can derive a general formula for powers of by looking at some examples. Table 1 You should understand Table 1 above .
What Are Imaginary Numbers? - HowStuffWorks
An imaginary number — basically, a number that, when squared, results in a negative number — was first established back in the 1400s and 1500s as a way to solve certain bedeviling equations. While initially thought of as sort of a parlor trick, in the centuries since, imaginary numbers have come to be viewed as a tool for conceptualizing the world in complex ways, and today are useful in ...

Imaginary Numbers Definition The number whose square results in negative results is called an Imaginary number. In simple words, the square root of negative numbers is called an imaginary number. They are called imaginary numbers as we cannot associate them with any real-life examples. They are represented by "i" and are pronounced as iota at its value is, i = √-1 Examples of Imaginary ...
