WebImaginary numbers do exist. Despite their name, they are not really imaginary at all. (The name dates back to when they were first introduced, before their existence was really understood. At that point in time, people were imagining what it would be like to have a number system that contained square roots of negative numbers, hence the name ... WebHe also created the concept of the imaginary number that is the square root of —1. Most agree that around 1777, Swiss mathematician Leonhard Euler (1707–1783) used “i” and “-i” (negative i) for the two different square roots of -1, thus eliminating some of the problems associated with notation when putting polynomials into categories.
