Whether you’re already slightly familiar with imaginary numbers and their purpose in mathematics or you’re a little confused or overwhelmed by the term, simply continue reading in order to discover a comprehensive guide to understanding and using imaginary numbers. Which are sometimes to referred to as complex numbers.

A guide to understanding imaginary numbers:

A simple definition of the term imaginary numbers: An imaginary number refers to a number which gives a negative answer when it is squared. So if you assumed that the term imaginary numbers would refer to a complicated type of number, that would be hard to wrap your head around, think again.

While imaginary numbers are sometimes referred to as complex numbers, they aren’t as complex as you may think. If you’re interested in further understanding imaginary numbers, they are a form of a complex number that can not be classed as a real number and which have simply been multiplied by an imaginary unit, which is always referred to simply as i.

Why are imaginary numbers useful?

Imaginary numbers are used in a wide variety of scenarios. As examples imaginary numbers are often used in advanced calculus and to solve advanced algebraic equations. Imaginary numbers are normally used to stand in for calculations that have to be worked out at a later stage of your equation solving.

In these scenarios you’ll often need to find further information out by performing other calculations, so that you can find the intended value of your imaginary number, which will always be expressed by the letter i.

Why is the unit when you are dealing with imaginary numbers important: When you’re dealing with the theoretical concept of imaginary numbers, the term unit is used to describe first term and is equivalent to how the numeral one, is the first number which exists.

In regards to imaginary units the formula for a single unit is squared root, minus one. However, in equations the term unit is more commonly referred to simply as the letter i. If you’re curious about why the letter i is used to denote the unit, the answer is that i stands for imaginary.

If a number is not an imaginary number, what could it be?

Numbers which aren’t imaginary numbers are defined as real numbers. However there is another subset of numbers which are classed as real numbers, which are referred to as complex numbers and which still feature imaginary numbers in their equations. One unique number is zero which is both an i number and a real number.

What is an example of an imaginary figure?

A simple example, which you can take a look at is 5i. The square root of which equates to -25.

In conclusion hopefully you found the information and answers that you were seeking and now fully understand what imaginary numerals are as well as what complex and real numbers are and how they all differ from each other.
