What is arctan(3/2)?
Answer
arctan(3/2) ≈
56.3099° ≈ 0.9828 rad
Range: arctan x is an angle strictly between −90° and 90°, so the answer is unique.
≈ — the value is not a table one; rounded to 4 decimal places.
3/2 = 1.5.
arctan(3/2) is the angle α in (−90°, 90°) with tan α = 3/2.
tan 56.3099° ≈ 1.5000
α = arctan(3/2) ≈ 56.3099°
P ≈ (0.5547, 0.8321)
T(1, 3/2) is where line OP meets the line x = 1; highlighted: tan α = 3/2.
