text: On this circle, if $P$ is the point such that the angle between the $x-$axis and $O P$ (measured in a counter-clockwise direction) is $\theta$, then the coordinates of $P$ are given by $x=\cos \theta$ and $y=\sin \theta$.
text: The angle $\theta$ between $O P$ and the $x$-axis, measured in a counter-clockwise direction, is called the argument of the complex number.
