WebArc tangent function. ATAN(x) returns the arc tangent of x. The arc tangent function is the inverse function of the tangent function and calculates the angle for a given tangent x. The result is an angle expressed in radians. To convert from radians to degrees, use the DEGREES function. Examples. ATAN(0) equals 0 . ATAN(1) equals 0.78539816 (=PI/4) WebJun 24, 2024 · Explanation: Use calculator: tanx = 1 2 --> arc x = 26∘57. 2arcx = 2(26.57) = 53∘13. tany = 1 7 --> arc y = 8∘13. 2arctan( 1 2) + arctan( 1 7) = 53∘13 +8∘13 = 61∘26. …
