What is arccos(3/5)?
Answer
arccos(3/5) ≈
53.1301° ≈ 0.9273 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.
3/5 = 0.6.
arccos(3/5) is the angle α in [0°, 180°] with cos α = 3/5.
cos 53.1301° ≈ 0.6000
α = arccos(3/5) ≈ 53.1301°
P = (0.6, 0.8)
P lies on the line x = 3/5 in the upper half of the circle, where sin α ≥ 0; highlighted: cos α = 3/5.
