Complex plane. {/eq}, Become a Study.com member to unlock this Clearly we can (re)define a real number as a complex number with an imaginary component that is zero (meaning that $0$ is a real number), but if one were to define an imaginary number as a complex number with real component zero, then that would also include $0$ among the pure imaginaries. A pure imaginary number is any complex number whose real part is equal to 0. Q ... [] Imaginary Numbers It can be done in the same manner as the previous ones, but there is a slightly easier way to do the problem.First, break up the fraction as follows. It can get a little confusing! So technically, an imaginary number is only the "\(i\)" part of a complex number, and a ~TildeLink() is a complex number that has no real part.
