What is arctan(0.7)?
Answer
arctan(0.7) ≈
34.9920° ≈ 0.6107 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(0.7) is the angle α in (−90°, 90°) with tan α = 0.7.
tan 34.9920° ≈ 0.7000
α = arctan(0.7) ≈ 34.9920°
P ≈ (0.8192, 0.5735)
T(1, 0.7) is where line OP meets the line x = 1; highlighted: tan α = 0.7.
