Imaginary element

An imaginary element typically refers to a concept within mathematics, particularly in the field of complex numbers. In this context, an imaginary number is a number that can be expressed as a real number multiplied by the imaginary unit \(i\), where \(i\) is defined as the square root of \(-1\). Thus, an imaginary number can be written in the form \(bi\), where \(b\) is a real number.
