Java Math tan() Method
The tan() method of Java Math class returns the trigonometric tangent of the specified angle.
Syntax:
public static double tan(double a)
Parameters:
The parameter ‘a’ represents an angle measured in radians.
Return Value:
The tan() method returns the tangent of the argument.
- It returns zero with same sign as argument, if the argument passed is zero.
- It returns NaN, if the argument is NaN or infinity.
Example 1:
public class JavaMathTanExample1 {
public static void main(String[] args) {
double a=30;
//return the tangent value for a
System.out.println("Tangent value: "+Math.tan(a));
}
}
Output:
Tangent value: -6.405331196646276
Example 2:
public class JavaMathTanExample2 {
public static void main(String[] args) {
//return the tangent value for Double.MIN_VALUE
double a=Double.MIN_VALUE;
System.out.println("Tangent value for "+a+" = "+Math.tan(a));
}
}
Output:
Tangent value for 4.9E-324 = 4.9E-324
Example 3:
public class JavaMathTanExample3 {
public static void main(String[] args) {
//returns zero with same sign as argument, if the argument passed is zero
double x = -0d;
System.out.println("Tangent value for "+x+" = "+Math.atan(x));
}
}
Output:
Tangent value for -0.0 = -0.0
Example 4:
public class JavaMathTanExample4 {
public static void main(String[] args) {
//return a tangent value for infinity
double x = -6/0.0d;
System.out.println("Tangent value for "+x+" = "+Math.tan(x));
}
}
Output:
Tangent value for -Infinity = NaN
Example 5:
public class JavaMathTanExample5 {
public static void main(String[] args) {
//return a tangent value for Nan
double x = Double.NaN;
System.out.println("Tangent value for "+x+" = "+Math.tan(x));
}
}
Output:
Tangent value for NaN = NaN
