Complex Number Plane

The complex number plane, also known as the Argand plane, is a fundamental concept in mathematics that extends the real number line into two dimensions. It is used to graph complex numbers, which consist of a real part and an imaginary part. The horizontal axis represents the real part of the complex number, while the vertical axis represents the imaginary part. This plane allows for the visualization and manipulation of complex numbers, enabling mathematicians and scientists to solve a wide range of complex problems in fields such as engineering, physics, and computer science.
