In the late 1500s, mathematicians discovered the existence of imaginary numbers. Imaginary numbers are needed to solve equations such as x^2 + 1 = 0. To distinguish imaginary numbers from real ones, mathematicians use the letteri, usually in italics, such asi, 3i, 8.4i, whereiis the square...
Essentially, an imaginary number is the square root of a negative number and does not have a tangible value. While it is not a real number — that is, it cannot be quantified on the number line — imaginary numbers are "real" in the sense that they exist and are used in math. ...
The moral of the story is that “complex numbers” are misnamed. While they are intimidating at first, they make things simple all over the place. Notably: trigonometry, anything with waves (electricity, light, sound), finding roots, streamlining math (often, but not always), and in quantum...

While imaginary numbers are meaningless in the "real world" of most individuals, they are indispensable in such fields as quantum mechanics, electrical engineering, computer programming, signal processing, and cartography. For perspective, consider that negative numbers were also once considered fictitious...

Imaginary numbers are also called complex numbers. When imaginary numbers are squared, the result is a negative number. Imaginary numbers are used in certain calculations, such as quadratic equations. They are the result of a real number multiplied by i, when i equals the square root of -1....
This position provides a foundation for the complex numbers and accounts for complex numbers in some equations of applied mathematics and physics. I also argue that complex numbers are fundamentally geometrical and can be described by geometric algebra, and that moreover the meaning of complex ...
