ATAN2(x,y)

This function gives the inverse function of Tangent in trigonometry with two arguments (x,y).
Here the arguments $x\neq 0$ & $y\neq 0$ .
Also ATan2(x,y) is the angle between the x-axis and the point given by the co-ordinate (x,y) on it.
Where x is the x-coordinate point & y is the y-coordinate point.
The angle is positive for counter-clockwise angles (upper half-plane, y > 0), and negative for clockwise angles (lower half-plane, y < 0).
Also the angle is with in $-\pi$ to $\pi$

-ATAN2 returns the error value when both xn and yn are 0. </font></font>
-If you want to convert the arctangent in degrees, multiply the result by 180/PI.
-Calci returns the arctangent of the particular x- and y-coordinates. It is the angle from the x-axis to a line with origin (0, 0) and with coordinates (xn, yn).
