Exponential form is a way to express complex numbers using the base of the natural logarithm, $e$, combined with trigonometric functions. In this representation, a complex number is expressed as $$z = r e^{i heta}$$, where $r$ is the magnitude of the complex number and $ heta$ is the argument or angle in radians. This form connects complex numbers to their geometric interpretation in the polar coordinate system, making it easier to perform operations like multiplication and division.
