What is arcsin(1)?
Answer
arcsin(1) =
90° = π/2
Range: arcsin x is an angle from −90° to 90°, so the answer is unique.
arcsin(1) is the angle α in [−90°, 90°] with sin α = 1.
α = arcsin(1) = 90°
P(cos 90°, sin 90°) = (0, 1)
P lies on the line y = 1 in the right half of the circle, where cos α ≥ 0; highlighted: sin α = 1.
