The IMAGINARY function returns the imaginary coefficient of a complex number in x + yi or x + yj text format.
|inumber||A complex number for which you want the imaginary coefficient. The inumber argument can be supplied to the IMAGINARY function as either:
Note: Use the COMPLEX function to convert real and imaginary coefficients into a complex number.
|2||3+4i||=IMAGINARY(A2)||4||Imaginary coefficient of the complex number 3+4i|

Within the real number scale, there is no such thing as the square root of a negative number. However, within the world of complex numbers, the ‘imaginary’ value, i is used to represent the square root of -1.
Therefore, the square root of any negative number can be represented by the square root of the number’s modulus, multiplied by i.
