Formula Description Returns
=ATAN2(-5;9) The angle (in radians) between the x-axis and a line from the origin to the point having X = -5 and Y = 9. 2.07789 (radians)
=DEGREES(ATAN2(12.3;12.3)) The angle (in radians) between the x-axis and a line from the origin to the point having X = 12.3 and Y = 12.3. To get the angle in degrees apply the DEGREES function to the result. The tangent of 45 degrees is 1. 45° (degrees)
=ATAN2(0;0) The angle (in radians) between the x-axis and a line from the origin to the point having X = 0 and Y = 0. 0 (radians)
=ATAN2(-5;-3)*180/PI() The angle (in radians) between the x-axis and a line from the origin to the point having X = -5 and Y = -3. Further, converting angle in radians to degrees by multiplying by 180/PI(). -149.036243467926° (degrees)
=DEGREES(ATAN2(-8;5)) The angle (in radians) between the x-axis and a line from the origin to the point having X = -8 and Y = 5. The function can be used in converting cartesian coordinates to polar coordinates. See the Fig. below 147.994616791916° (degrees)
