Parameters:
The x num and y num parameters are the x- and y-coordinates of the point whose arctangent you wish to compute.
Step By Step Guide of ATAN2 function
Example :
It is important to note that the angle returned by the Atan2 function might be positive (indicating a counterclockwise angle from the x-axis) or negative (representing a clockwise angle from the x-axis). This outcome is presented in radians. It is worth noting that the Excel Degrees function is used in the example in cell A4 to convert the computed angle from radians to degrees.
Key Points
- #DIV/0!-Occurs if both the x num and y num parameters are equal to 0.
- #VALUE!-This error occurs if one or both of the given arguments are not numeric.
