Description
ATAN2
ATAN2 (xn, yn).
Where xn is the x-coordinate and yn is the y-coordinate of that particular point.
· ATAN2 returns the error value when both xn and yn are 0.
· 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).
| Column1 | Column2 | Column3 | Column4 | |

Lets see an example in (Column1, Row 1 and Column 2, Row1)
ATAN2 (A, B)
ATANH (C1R1, C2R1)'
That is ATAN2 (-1, 1) is -0.7854
