For an historical account of complex numbers refer to appendix 2, page 28 real life context complex numbers are useful in representing a phenomenon that. In the complex number system, the absolute value of a number a + bi or (a,b ) is defined in an analogous way as the distance from the origin (0,0) to the point p. Origin of the imaginary unit square roots of positive real numbers lead us to the study of rational and irrational numbers by including the imaginary square roots .
Just because imaginary numbers don't exist, it doesn't mean they are completely useless. At this early period of history, complex numbers were not well understood, with many the square root of a nonpositive real number is an imaginary number. Similarly, the factorials of imaginary numbers are complex numbers dutka ( 1991) gave an account of the early history of the factorial function.
