What is arccot(1)?
Answer
arccot(1) =
45° = π/4
Range: arccot x is an angle strictly between 0° and 180°, so the answer is unique.
arccot(1) is the angle α in (0°, 180°) with cot α = 1.
α = arccot(1) = 45°
P(cos 45°, sin 45°) = (√2/2, √2/2)
C(1, 1) is where line OP meets the line y = 1; highlighted: cot α = 1.
