Asin
From Real Software Documentation
Method
Returns the arcsine of the value specified.
Syntax
result = Asin(value)
| Part | Type | Description |
|---|---|---|
| result | Double | The arc sine of value. |
| 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. |
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
Const PI = 3.14159265358979323846264338327950
d = Asin(.5) //returns 0.5235988
d = Asin(.5)*180/PI //returns 30
