Acos
From Real Software Documentation
Method
Returns the arccosine of the value specified. The arccosine is the angle whose cosine is value. The returned angle is given in radians.
Syntax
result = Acos(value)
| Part | Type | Description |
|---|---|---|
| result | Double | The arc cosine of value. |
| value | Double | The value you want the arc cosine of. |
Note
The Acos function returns the angle (in radians) of the cosine passed to it. To convert the result from radians to degrees, multiply it by 180/Pi.
Examples
This example uses the Acos function to return the arc cosine of a number.
Dim d As Double
Const Pi = 3.14159265358979323846264338327950
d = Acos(.5) // returns 1.0471976
d = Acos(.5)*180/PI // returns 60
Const Pi = 3.14159265358979323846264338327950
d = Acos(.5) // returns 1.0471976
d = Acos(.5)*180/PI // returns 60
