Description

Returns the angle between the x-axis and a line segment from the origin (0,0) to specified coordinate pair (`x`,`y`), in radians.

Sample Usage

ATAN2(5,4)

ATAN2(A3)

Syntax

ATAN2(x,y)

  • x - The x coordinate of the endpoint of the line segment for which to calculate the angle from the x-axis.

  • y - The y coordinate of the endpoint of the line segment for which to calculate the angle from the x-axis.

Notes

  • The DEGREES function can be used to convert the result of ATAN into degrees.

Step 1: To use the ATAN2 Formula, simply begin with your edited Excellentable:
