Acos
Finds the arccosine of an angle
result = Acos( number )
number
The arccosine of number in radians, in the range [0..Pi].
Acos returns the arccosine of the argument number as a Double within the range of 0 to Pi. The arccosine is the inverse of the Cos function. The returned angle is measured in radians (not degrees).
The output would look like:
Syntax
Usage
result = Acos( number )
Parameters
number
A cosine value in the range [-1..1].
Return Value
The arccosine of number in radians, in the range [0..Pi].
Description
Acos returns the arccosine of the argument number as a Double within the range of 0 to Pi. The arccosine is the inverse of the Cos function. The returned angle is measured in radians (not degrees).
Example
Dim h As Double
Dim a As Double
Input "Please enter the length of the hypotenuse of a triangle: ", h
Input "Please enter the length of the adjacent side of the triangle: ", a
Print ""
Print "The angle between the sides is"; Acos ( a / h )
Sleep
Dim a As Double
Input "Please enter the length of the hypotenuse of a triangle: ", h
Input "Please enter the length of the adjacent side of the triangle: ", a
Print ""
Print "The angle between the sides is"; Acos ( a / h )
Sleep
The output would look like:
Please enter the length of the hypotenuse of a triangle: 5 Please enter the length of the adjacent side of the triangle: 4 The angle between the sides is 0.6435011087932843
