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.

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
```
