Determines the arcsine of a number. The arcsine is the angle whose sine is number.
The arcsine of a number, in radians.
ASin(number)
Parameter | Description |
---|---|
number |
Sine of an angle. The value must be between -1 and 1, inclusive. |
The range of the result is -π/2 to π/2 radians. To convert degrees to radians, multiply degrees by π/180. To convert radians to degrees, multiply radians by 180/π.
