| - | * The range of **arg** must be between -1 and 1, because the sine of any angle can't be outside that range. | + | * The range of $prm[arg] must be between -1 and 1, because the sine of any angle can't be outside that range. |
| - | * The result is always between -[[constants/PI_BY_TWO]] and **PI_BY_TWO**, or **NaN** if the argument is out of the valid range. | + | * The result is always between -$lct[PI_BY_TWO] and $ct[PI_BY_TWO, or $nan if the argument is out of the valid range. |
