What is arccos(0.1)?
Answer
arccos(0.1) ≈
84.2608° ≈ 1.4706 rad
Range: arccos x is an angle from 0° to 180°, so the answer is unique.
≈ — the value is not a table one; rounded to 4 decimal places.
arccos(0.1) is the angle α in [0°, 180°] with cos α = 0.1.
cos 84.2608° ≈ 0.1000
α = arccos(0.1) ≈ 84.2608°
P ≈ (0.1, 0.9950)
P lies on the line x = 0.1 in the upper half of the circle, where sin α ≥ 0; highlighted: cos α = 0.1.
