Online arcsin(x) calculator. Inverse sine calculator and how use this calculator.

The arcsine function is the inverse function of y = sin(x).

how to calculat The arcsine is used to obtain an angle from the sine trigonometric ratio, which is the ratio between the side opposite to the angle and the longest side of the triangle. The function spans from -1 to 1, and so do the results from our arcsin calculator. The range of the angle values is usually between -90�� and 90��

arcsin(*y*) = sin^{-1}(*y*) = *x* + 2*kπ*

For every

*k* = {...,-2,-1,0,1,2,...}<

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°
