Online arcsin calculator, arc sine function calculator, can calculate angle from arcsin(x) value.
(-1≤x≤1)
(°)
(rad)
The arcsine function is the inverse function of y = sin(x).
arcsin(y) = sin-1(y) = x + 2kπ
For example, If the sine of 30° is 0.5:
sin(30°) = 0.5
Then the arcsine of 0.5 is 30°:
arcsin(0.5) = sin-1(0.5) = 30°
