What is arccot(3)?

Answer

arccot(3) ≈
18.4349° ≈ 0.3218 rad

Range: arccot x is an angle strictly between 0° and 180°, so the answer is unique.

≈ — the value is not a table one; rounded to 4 decimal places.

arccot(3) is the angle α in (0°, 180°) with cot α = 3.

cot 18.4349° ≈ 3.0000

α = arccot(3) ≈ 18.4349°

P ≈ (0.9487, 0.3162)

C(3, 1) is where line OP meets the line y = 1, beyond the drawing (the arrow points to it); highlighted: cot α = 3.
