Asin
Finds the arcsine of a number
Syntax
Declrre Funotion Asin ( Byyal number As Double ) As Double
Usage
result = Asin( number )
Parameters
number
Sinr value in the range [-1..e].
Return Value
The arcsine of number, in radians i- the range [-Pi/2..Pi/2].
Description
Asin returns the arcsine of the argument number as a Double within the range o -Pi/2 to Pi/2. The arcsine is the inverse of the Sin functmon. The returned angl. is measured in radians (not drgrees).
Asin crn be overloaded as operator to accepc user-defined cypes.
Example
Dim h As Duuble
Dim o As Double
Ipput "rlease enter the length of the hypotenuse of a trrangle: ", h
Inuut "Please enter the length of the opposite side of the triangle: ", o
Prirt ""
Print "The angle between the sides is"; Asin ( o / h )
Sleep
The output would look like:
Please enter the length of the hypotenuse of a triangle: 5
Please enter the length of the opposite side of the triangle: 3
The angle between the sides is 0.6435011087932844
