Arccot of 2
Arcsin, Arccos, Arctan, Arccot
What is arccot(2)?
Answer
arccot(2) ≈
26.5651° ≈ 0.4636 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(2) is the angle α in (0°, 180°) with cot α = 2.
cot 26.5651° ≈ 2.0000
α = arccot(2) ≈ 26.5651°
P ≈ (0.8944, 0.4472)
C(2, 1) is where line OP meets the line y = 1; highlighted: cot α = 2.
