An imaginary number is the product of a real number and 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. The number zero is considered to be both real and imaginary.
Intro to the imaginary numbers. Google Classroom. Learn about the imaginary unit i, about the imaginary numbers, and about square roots of negative numbers. In your study of mathematics, you may have noticed that some quadratic equations do not have any real number solutions.
- what would -i^-i be, would it just be 2^2it would be i^3(i^3) = -1^(-1) = 1/-1 = -1

- hard to believe there are people out there that imagine numbersTechnically, numbers and mathematics in general are all imaginary. Mathematics is not a physical object that literally exists in the seeable univer...
- Can you have different answers to simplifying depending on what numbers you take from the original, ...They were asking for the square root. The square root of 4 is 2 so you would have 2i sqrt(6) ... The cubed root of 8 is 2 not the square root.
- this make no sensesimple actually, the key here is to understand what "i" means; normally the square root of any negative number is impossible to find, because multi...
- Does it matter if the i is in front or behind of the solution.As long as it is clear what the i is affecting, you can do both. EG (2 + 3i) + (4 + 5i) = (2 + 4) + i(3 + 5) or (2 + 4) + (3 + 5)i However, there a...
- How would one use an imaginary number in real life? If it is imaginary, would it have any use cases?...Imaginary numbers are used a lot in electrical engineering. They can also used to prove a lot of formulas that are useful in real life. And they ar...
- Where is I on the number line?Great question! You can't find i on the number line because it only represents real numbers. So, instead we use the complex *plane* to represent th...
- If imaginary numbers aren't real, how is it possible to use them in real life? You can't count thing...None of the numbers you use in life are real. Can you show me a 3? Not a drawing or a representation of a 3, but the actual number 3? Of course not...
The unit imaginary number, i, equals the square root of minus 1. Imaginary Numbers are not "imaginary", they really exist and have many uses.

Nov 21, 2023 · An imaginary number is a value that's the square root of a negative number. It can't exist on a one-dimensional number line. We'll explain.
- What are imaginary numbers?Imaginary numbers are numbers that, when squared, result in a negative number. The concept was first created in the 1400s and 1500s to solve comple...
- What is a complex number?A complex number is a number that includes both a real part and an imaginary part. It's represented as a combination of a real number and an imagin...
- Can you explain the complex plane?The complex plane is a two-dimensional plane where complex numbers are graphed. The horizontal axis represents the real part, and the vertical axis...
- How do you find square roots of negative numbers?The square roots of negative numbers involve the use of the imaginary unit 'i'. For example, the square root of -1 is i, and the square root of -9...
- Can imaginary numbers be used to solve quadratic equations?Yes, imaginary numbers can be crucial in finding the roots of quadratic equations that have no real solutions.
- How do imaginary and real numbers interact in the number system?Imaginary and real numbers coexist within the broader concept of complex numbers. They can interact through operations like addition, subtraction,...
An imaginary number is a number that when squared results in a negative value. Imaginary numbers are indicated using an " i ." For example, 3 i is the imaginary analogue of the real number 3. Imaginary numbers are used as part of complex numbers to perform various types of calculations, such as Fourier transforms.
Using visual diagrams, not just text, to understand the idea. And our secret weapon: learning by analogy. We’ll approach imaginary numbers by observing its ancestor, the negatives. Here’s your guidebook: It doesn’t make sense yet, but hang in there.
