Mar 14, 2024 · Imaginary numbers are numbers as the name suggests are the number that is not real numbers. All the numbers real and imaginary come under the categories of complex numbers. Imaginary numbers are very useful in solving quadratic equations and other equations whose solutions can not easily be found using general rules.
Imaginary numbers are numbers that result in a negative number when squared. They are also defined as the square root of negative numbers. An imaginary number is the product of a non-zero real number and the imaginary unit "i" (which is also known as "iota"), where i = √ (-1) (or) i 2 = -1. Let's try squaring some real numbers: (−2) 2 = −2×−2 = 4.
