What are the imaginary numbers?
We know that the imaginary numbers has to do with the numbers that we can be not be able to find on the number line. These are not real numbers but they are very important in the process of computation. There are two parts of a complex number. We have the imaginary part and we have the real part.
It is sometimes possible that we can be able to represent the complex number by the use of an Argand diagram which shows the complex number in the polar form.
