Java.lang.StrictMath.tan() Method


Advertisements


Description

The java.lang.StrictMath.tan() method returns the trigonometric tangent of an angle.It include these cases −

  • If the argument is NaN or an infinity, then the result is NaN.
  • If the argument is zero, then the result is a zero with the same sign as the argument.

Declaration

Following is the declaration for java.lang.StrictMath.tan() method

public static double tan(double a)

Parameters

a − This is an angle, in radians.

Return Value

This method returns the tangent of the argument.

Exception

NA

Example

The following example shows the usage of java.lang.StrictMath.tan() method.

package com.tutorialspoint;

import java.lang.*;

public class StrictMathDemo {

   public static void main(String[] args) {

      double d1 = (45*Math.PI)/180 , d2 = 0.0;
   
      // returns the trigonometric tangent of an angle
      double tanValue = StrictMath.tan(d1); 
      System.out.println("tangent value of d1 : " + tanValue);

      tanValue = StrictMath.tan(d2); 
      System.out.println("tangent value of d2 : " + tanValue);
   }
}

Let us compile and run the above program, this will produce the following result −

tangent value of d1 : 0.9999999999999999
tangent value of d2 : 0.0
