realaxis
Realaxis refers to the real axis in the complex plane. It is the set of all complex numbers with zero imaginary part and can be written as {x ∈ R} or {x + 0i | x ∈ R}. In a standard Argand diagram, it corresponds to the horizontal axis and is often identified with the real number line.
As a subset of the complex plane, the Realaxis is a one-dimensional real manifold and is topologically
Operations and transformations: Adding a real number or multiplying by a real scalar maps the Realaxis into
Applications: In visualization, the Realaxis is the x-axis of the Argand plane. It provides a reference for
