What is arcsin(3/4)?
Answer
arcsin(3/4) ≈
48.5904° ≈ 0.8481 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.
3/4 = 0.75.
arcsin(3/4) is the angle α in [−90°, 90°] with sin α = 3/4.
sin 48.5904° ≈ 0.7500
α = arcsin(3/4) ≈ 48.5904°
P ≈ (0.6614, 0.75)
P lies on the line y = 3/4 in the right half of the circle, where cos α ≥ 0; highlighted: sin α = 3/4.
