Function operation:
The ARCSIN function performs the action of the arcsine trigonometric function. The real value is specified at input x, and then the arc sine function value is calculated. If the input value is outside the range of the function domain, the error output is activated and the y output is -π / 2 for x <-1 or π / 2 for x> 1.
R registers and M markers used: none
