# Imaginary Number

In mathematics, there are many Numbers one of them is imaginary number. Imaginary Number definition says that it is a type of number which is always less than or equal to zero whenever it is squared. Let iy, is an imaginary number when it is added to a real number, which is x, then their addition results into a Complex Number of the form x + iy, where x and y are known as the real part and the imaginary part of that complex number.

Let us show you an example  of imaginary number. If we have a negative number in the Square root then we cannot solve it until we remove the negative sign and we can do that but when we remove the negative sign we have to put a imaginary unit before the square root.
So in imaginary numbers definition, we have an example: √ -36 which is an imaginary number and it’s square root is -36 but imaginary number can be written as a real number by putting an imaginary unit before the square root. In imaginary number, we put an imaginary unit because of the property i2 = -1.

Imaginary number definition has one more important Point to share and that is a complex number can be equal to an imaginary number when the real part of the complex number is zero.
Imaginary numbers definition says that imaginary number has many useful applications in complex number field.
Imaginary number has many applications and they are: Imaginary number is useful in construction of non-real complex numbers, which plays a very important role in applications of science and technology and it has many other applications in control theory, fluid dynamics, quantum mechanics, vibration analysis, electromagnetism, signal processing and cartography.
So, finally we have discussed all the points of imaginary numbers definition.

## Imaginary numbers rules

In simple mathematics, square root of a positive number is defined as a number that gives a specify number when multiplied by itself. A number can be positive or negative. If we want to find the Square root of a negative number then it can be calculated with the help of Complex Number.

Complex number is a Combination of two Numbers or parts, one is real number...Read More
