What is arcsin(−√3/2)?
Answer
arcsin(−√3/2) =
−60° = −π/3
Range: arcsin x is an angle from −90° to 90°, so the answer is unique.
arcsin(−√3/2) is the angle α in [−90°, 90°] with sin α = −√3/2.
arcsin(−√3/2) = −arcsin(√3/2) = −60°
sin(−60°) = −√3/2 ✓
α = arcsin(−√3/2) = −60°
P(cos(−60°), sin(−60°)) = (1/2, −√3/2)
P lies on the line y = −√3/2 in the right half of the circle, where cos α ≥ 0; highlighted: sin α = −√3/2.
| Function | Degrees | Radians |
|---|---|---|
| arcsin(−√3/2) | −60° | −π/3 |
| arccos(−√3/2) | 150° | 5π/6 |
| arctan(−√3/2) | ≈ −40.8934° | ≈ −0.7137 |
| arccot(−√3/2) | ≈ 130.8934° | ≈ 2.2845 |
