What is arcsin(1/4)?
Answer
arcsin(1/4) ≈
14.4775° ≈ 0.2527 rad
Range: arcsin x is an angle from −90° to 90°, so the answer is unique.
≈ — the value is not a table one; rounded to 4 decimal places.
1/4 = 0.25.
arcsin(1/4) is the angle α in [−90°, 90°] with sin α = 1/4.
sin 14.4775° ≈ 0.2500
α = arcsin(1/4) ≈ 14.4775°
P ≈ (0.9682, 0.25)
P lies on the line y = 1/4 in the right half of the circle, where cos α ≥ 0; highlighted: sin α = 1/4.
| Function | Degrees | Radians |
|---|---|---|
| arcsin(1/4) | ≈ 14.4775° | ≈ 0.2527 |
| arccos(1/4) | ≈ 75.5225° | ≈ 1.3181 |
| arctan(1/4) | ≈ 14.0362° | ≈ 0.2450 |
| arccot(1/4) | ≈ 75.9638° | ≈ 1.3258 |
