In mathematics, the complex plane is the plane formed by the complex numbers, with a Cartesian coordinate system such that the horizontal x-axis, called the real axis, is formed by the real numbers, and the vertical y-axis, called the imaginary axis, is formed by the imaginary numbers.
en.wikipedia.org/wiki/Complex_planeA Complex Number is a combination of a Real Number and an Imaginary Number: A Real Number is the type of number we use every day. Examples: 12.38, ½, 0, −2000
www.mathsisfun.com/algebra/complex-plane.htmlInstead of just using the regular number line for real numbers, the complex plane adds another line going up and down, called the imaginary axis. This creates a grid where every point shows a complex number. Complex numbers have two parts: A real part (like numbers we use every day, such as 3 or -5).
apluscalculus.com/blog/all-about-complex-plane/The real axis is the line in the complex plane corresponding to zero imaginary part, I[z]=0. Every real number corresponds to a unique point on the real axis.

Complex numbers
In complex analysis, the complex numbers are customarily represented by the symbol z, which can be separated into its real (x) and imaginary (y) parts: 展开When discussing functions of a complex variable it is often convenient to think of a cut in the complex plane. This idea arises naturally in several different contexts.

2023年3月4日 · In the complex plane, the real numbers lie on the horizontal or real axis, and pure imaginary numbers lie on the vertical or imaginary axis. To plot a complex number \(a+b i\) we move \(a\) units from the origin in the horizontal …
Image of imaginary axis under $f$ is either real axis or imaginary axis

2016年10月3日 · Complex numbers are 2-dimensional with a real part and an imaginary part. Thus the graph would need three dimensions to represent (the x-axis for the {ix} input. A y-axis for the real part of the complex output and a z …
So where exactly is the imaginary axis? : r/askmath
You construct a real axis that is not so different than the x-axis or the polar axis. Once you move on to 2D, instead of a y-axis but similar to it, you construct an imaginary axis. Now, you can describe a position in 2D with z=a+bi as …
