What is arctan(7)?
Answer
arctan(7) ≈
81.8699° ≈ 1.4289 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(7) is the angle α in (−90°, 90°) with tan α = 7.
tan 81.8699° ≈ 7.0000
α = arctan(7) ≈ 81.8699°
P ≈ (0.1414, 0.9899)
T(1, 7) is where line OP meets the line x = 1, beyond the drawing (the arrow points to it); highlighted: tan α = 7.
