What is arctan(5/3)?
Answer
arctan(5/3) ≈
59.0362° ≈ 1.0304 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(5/3) is the angle α in (−90°, 90°) with tan α = 5/3.
tan 59.0362° ≈ 1.6667
α = arctan(5/3) ≈ 59.0362°
P ≈ (0.5145, 0.8575)
T(1, 5/3) is where line OP meets the line x = 1; highlighted: tan α = 5/3.
