The square root of negative numbers (also known as imaginary numbers) is a mathematical construct represented by the symbol ‘i’, where i^2 = -1. It is used extensively in various fields, such as electrical engineering and quantum mechanics.
The concept of imaginary numbers was first introduced by Italian mathematician Gerolamo Cardano in the 16th century. Since then, it has become an integral part of mathematics, playing a crucial role in solving complex equations and providing insights into the behavior of physical systems.
