WebAn imaginary number is a real number multiplied by 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.By definition, zero is considered to be both real and imaginary. Originally coined in the 17th century by René Descartes as a derogatory … WebThe reason for getting rid of the complex parts of the equation in the denominator is because its not easy to divide by complex numbers, so to make it a real number, which is a whole lot easier to divide by, we have to multiply it by a number that will get rid of all the imaginary numbers, and a good number to use is the conjugate.
