Returns the inverse sine of x, in that if sin(x)=n, arcsin(n)=x, and the resulting number will be between -pi/2 and pi/2.

NOTE:This will only accept a value between -1 and 1 (anything else will throw an error).

arcsin(x);

Argument | Description |
---|---|

x | The angle (in radians) to return the inverse sine of. |

Real

val = arcsin( 0 );

This will set val to 0.
