.acos()
The Math.acos()
method returns the inverse cosine (or arccosine) of the argument in radians.
Syntax
Math.acos(n)
n
is a double
between 0 and 1.
Example
The following example uses Math.acos()
to return the inverse cosine of 0.0
and 1.0
:
class Main {public static void main(String[] args) {double arg1 = 0.0;double arg2 = 1.0;System.out.println(Math.acos(arg1));System.out.println(Math.acos(arg2));}}
This will produce the following output:
1.57079632679489660.0
