ATN2
returns the angle between the positive x-axis and the ray from the origin to the point (y, x), where x and y are the parameter values.
The value returned is an angle measured in radians.
The angle lies between the positive x-axis and the ray from the origin to the point.
This example returns the angle between the positive x-axis and the ray from the origin to the point (y, x), where x and y are the two parameter values.
