The arcsine of x is defined as the inverse sine function of x. Please change the value below and click "Calculate" button to see the results.
The arcsine function is the inverse function of y = sin(x)
Formula: arcsin(y) = sin-1(y) = x + 2kπ
Arcsin Range: between 0 and π radians
If the parameter x is outside the range -1 to 1, the results will be 'NaN'.
