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

xyOP

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.
