What is arctan(0.1)?
Answer
arctan(0.1) ≈
5.7106° ≈ 0.0997 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(0.1) is the angle α in (−90°, 90°) with tan α = 0.1.
tan 5.7106° ≈ 0.1000
α = arctan(0.1) ≈ 5.7106°
P ≈ (0.9950, 0.0995)
T(1, 0.1) is where line OP meets the line x = 1; highlighted: tan α = 0.1.
| Function | Degrees | Radians |
|---|---|---|
| arcsin(0.1) | ≈ 5.7392° | ≈ 0.1002 |
| arccos(0.1) | ≈ 84.2608° | ≈ 1.4706 |
| arctan(0.1) | ≈ 5.7106° | ≈ 0.0997 |
| arccot(0.1) | ≈ 84.2894° | ≈ 1.4711 |
