Acos Function
Returns the arccosine of the value specified. The arccosine is the angle whose cosine is value.
Syntax
result = Acos( value )
Parameters | ||
value |
The value you want the arc cosine of. |
The returned angle is given in radians.
Notes
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
