Argand diagram

An Argand diagram is the graphical representation of complex numbers written in polar coordinates. For example, if $z\\in\\mathbb{C}$ is a complex number, then $z$ can be written as $re^{i\\theta}$ , where $r$ is the length of $z$ considered as a vector $(x,y)\\in\\mathbb{R}^{2}$ , with $z=x+yi$ , and $\\theta$ is the value such that $\\tan\\theta=\\frac{y}{x}$ , and can be interpreted as the angle $z$ makes with the $x$ -axis. The Argand diagram of $z$ is thus
