Asin

FreeBASIC

Asin
 
Finds the arcsine of a number

Syntax

Declare Function Asin ( ByVal number As Double ) As Double

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


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
