Trigonometric methods in Java

The java.lang.Math class contains methods for performing basic numeric operations such as the trigonometry, logarithm, etc.

The following are some of the methods.

Let us see an example of acos() method.

Example

 Live Demo

public class Demo {
   public static void main(String args[]) {
      double val = Math.PI / 2;
      val = Math.toRadians(val);
      System.out.println("Math.acos(" + val + ") = " + Math.acos(val));
   }
}

Output

Math.acos(0.027415567780803774) = 1.5433773235341761

Let us see an example of asin() method.

Example

 Live Demo

public class Demo {
   public static void main(String args[]) {
      double val = Math.PI / 2;
      val = Math.toRadians(val);
      System.out.println("Math.asin(" + val + ") = " + Math.asin(val));
   }
}

Output

Math.asin(0.027415567780803774) = 0.02741900326072046

Let us see an example of log() method.

Example

 Live Demo

public class Demo {
   public static void main(String args[]) {
      double val1 = 39564.9;
      double val2 = 1;
      System.out.println("Math.log(" + val1 + ") = " + Math.log(val1));
      System.out.println("Math.log(" + val2 + ") = " + Math.log(val2));
   }
}

Output

Math.log(39564.9) = 10.585697640553684
Math.log(1.0) = 0.0
