![]() ![]() Is a distance between point 0 and complex point on the complex plane, and φ is an angle between positive real axis and the complex vector (argument). Where r - absolute value of complex number: a - corresponds to real part, b - imaginary part. Where a and b - real numbers, i - imaginary unit, so that i 2=-1. It is used in several ways in complex number defining. 19th century No one questions the exactness of the results which we obtain by the Calculus of imaginary quantities, although they are but algebraic forms, and the hieroglyphics of unreal quantities. ![]() This circumstance make use to think of the numbers, which are inherently impossible and are usually called imaginary, because they are only in the mind can be imagined. The negative number square roots cannot belong to the real numbers, so they are unreal numbers.
