Java Math tan() method with Examples
The java.lang.Math.tan() returns the trigonometric tangent of an angle.
- If the argument is NaN or an infinity, then the result returned is NaN.
- If the argument is zero, then the result is a zero with the same sign as the argument.
Syntax :
public static double tan(double angle) Parameters : The function has one mandatory parameter angle which is in radians.
Returns :
The function returns the trigonometric tangent of an angle.
Example 1 : To show the working of java.lang.Math.tan() method.
// Java program to demonstrate working // of java.lang.Math.tan() method import java.lang.Math; class Gfg { // driver code public static void main(String args[]) { double a = 30 ; // converting values to radians double b = Math.toRadians(a); System.out.println(Math.tan(b)); a = 45 ; // converting values to radians b = Math.toRadians(a); System.out.println(Math.tan(b)); a = 60 ; // converting values to radians b = Math.toRadians(a); System.out.println(Math.tan(b)); a = 0 ; // converting values to radians b = Math.toRadians(a); System.out.println(Math.tan(b)); } } |
Output :
0.5773502691896257 0.9999999999999999 1.7320508075688767 0.0
Example 2 : To show the working of java.lang.Math.tan() method when an argument is NAN or infinity.
// Java program to demonstrate working // of java.lang.Math.tan() method infinity case import java.lang.Math; public class GFG { public static void main(String[] args) { double positiveInfinity = Double.POSITIVE_INFINITY; double negativeInfinity = Double.NEGATIVE_INFINITY; double nan = Double.NaN; double result; // Here argument is negative infinity, // output will be NaN result = Math.tan(negativeInfinity); System.out.println(result); // Here argument is positive infinity, // output will also be NaN result = Math.tan(positiveInfinity); System.out.println(result); // Here argument is NaN, output will be NaN result = Math.tan(nan); System.out.println(result); } } |
Output :
NaN NaN NaN
