Asin Function

Returns the arcsine of the value specified.

Syntax
result = Asin( value )

Parameters
value | Double | The value you want the arc sine of. Value is the Sin of the angle you want and must be between -1 and 1.

Return Value
Result | Double | The arc sine of value.

# Notes

The arcsine is the angle whose sine is value. The Asin function returns the angle (in radians) of the sine passed to it. To express the arcsine in degrees, multiply the result by 180/PI.

# Examples

This example uses the Asin function to return the arcsine of a number.

Dim d as Double
Const PI=3.14159265358979323846264338327950
d=Asin(.5) //returns 0.5235988
d=Asin(.5)*180/PI //returns 30
