# How to Use ATAN2 in Google Sheets in 2020?

ATAN2The ATAN2 function returns the angle between the x-axis and a line segment from the origin (0,0) to the specified coordinate pair (`x`,`y`), in radians.
Sample Usage

ATAN2(4,3)

ATAN2(A2)

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.
