What is arctan(5/6)?
Answer
arctan(5/6) ≈
39.8056° ≈ 0.6947 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.
arctan(5/6) is the angle α in (−90°, 90°) with tan α = 5/6.
tan 39.8056° ≈ 0.8333
α = arctan(5/6) ≈ 39.8056°
P ≈ (0.7682, 0.6402)
T(1, 5/6) is where line OP meets the line x = 1; highlighted: tan α = 5/6.
