What is arctan(3/5)?
Answer
arctan(3/5) ≈
30.9638° ≈ 0.5404 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.
3/5 = 0.6.
arctan(3/5) is the angle α in (−90°, 90°) with tan α = 3/5.
tan 30.9638° ≈ 0.6000
α = arctan(3/5) ≈ 30.9638°
P ≈ (0.8575, 0.5145)
T(1, 3/5) is where line OP meets the line x = 1; highlighted: tan α = 3/5.
