Asin
Finds the arcsine of a number
result = Asin( number )
number
The arcsine of number, in radians, in the range [-Pi/2..Pi/2].
Asin returns the arcsine of the argument number as a Double within the range of -Pi/2 to Pi/2. The arcsine is the inverse of the Sin function. The returned angle is measured in radians (not degrees).
The output would look like:
Syntax
Usage
result = Asin( number )
Parameters
number
Sine value in the range [-1..1].
Return Value
The arcsine of number, in radians, in the range [-Pi/2..Pi/2].
Description
Asin returns the arcsine of the argument number as a Double within the range of -Pi/2 to Pi/2. The arcsine is the inverse of the Sin function. The returned angle is measured in radians (not degrees).
Example
Dim h As Double
Dim o As Double
Input "Please enter the length of the hypotenuse of a triangle: ", h
Input "Please enter the length of the opposite side of the triangle: ", o
Print ""
Print "The angle between the sides is"; Asin ( o / h )
Sleep
Dim o As Double
Input "Please enter the length of the hypotenuse of a triangle: ", h
Input "Please enter the length of the opposite side of the triangle: ", o
Print ""
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
