What is arccos(0.7)?
Answer
arccos(0.7) ≈
45.5730° ≈ 0.7954 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(0.7) is the angle α in [0°, 180°] with cos α = 0.7.
cos 45.5730° ≈ 0.7000
α = arccos(0.7) ≈ 45.5730°
P ≈ (0.7, 0.7141)
P lies on the line x = 0.7 in the upper half of the circle, where sin α ≥ 0; highlighted: cos α = 0.7.
