What is arctan(3/4)?
Answer
arctan(3/4) ≈
36.8699° ≈ 0.6435 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.
3/4 = 0.75.
arctan(3/4) is the angle α in (−90°, 90°) with tan α = 3/4.
tan 36.8699° ≈ 0.7500
α = arctan(3/4) ≈ 36.8699°
P = (0.8, 0.6)
T(1, 3/4) is where line OP meets the line x = 1; highlighted: tan α = 3/4.
