What is arccot(1/2)?

Answer

arccot(1/2) ≈
63.4349° ≈ 1.1071 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.

1/2 = 0.5.

arccot(1/2) is the angle α in (0°, 180°) with cot α = 1/2.

cot 63.4349° ≈ 0.5000

xyOP

α = arccot(1/2) ≈ 63.4349°

P ≈ (0.4472, 0.8944)

C(1/2, 1) is where line OP meets the line y = 1; highlighted: cot α = 1/2.
