What is arccos(0)?
Answer
arccos(0) =
90° = π/2
Range: arccos x is an angle from 0° to 180°, so the answer is unique.
arccos(0) is the angle α in [0°, 180°] with cos α = 0.
α = arccos(0) = 90°
P(cos 90°, sin 90°) = (0, 1)
P lies on the line x = 0 in the upper half of the circle, where sin α ≥ 0; highlighted: cos α = 0.
