The method returns the arccosine of the specified double value.
double acos(double d)
Here is the detail of parameters −
d − A double data type.
This method returns the arccosine of the specified double value.
public class Test { public static void main(String args[]) { double degrees = 45.0; double radians = Math.toRadians(degrees); System.out.format("The value of pi is %.4f%n", Math.PI); System.out.format("The arccosine of %.4f is %.4f degrees %n", Math.cos(radians), Math.toDegrees(Math.acos(Math.cos(radians)))); } }
This will produce the following result −
The value of pi is 3.1416 The arccosine of 0.7071 is 45.0000 degrees
