Java.lang.StrictMath.tan() Method

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
