These are respectively found the imaginary axis and real axis.
True, I know. But they do count in the set of all complex numbers.

About Euler's identity, e^ipi is a real number, -1. This means that some combinations of reals and imaginaries can give still realsor imaginaries, not complex numnbers, even when no part of the number is zero.
