You will see that, in general, you proceed as in real numbers, but using i 2 =−1 where appropriate. Complex Number can be considered as the super-set of all the other different types of number. Rotation >> Each point is represented by a complex number, and each line or circle is represented by an equation in terms of some complex z and possibly its conjugate z. the imaginary numbers. COMPLEX NUMBER Consider the number given as P =A + −B2 If we use the j operator this becomes P =A+ −1 x B Putting j = √-1we get P = A + jB and this is the form of a complex number.
