Online Java tanh() function

public class Main { public static void main(String[] args) { double a = 30; // converting values to radian double b = Math.toRadians(a); // return the trigonometric sine of a System.out.println("Sine value of a is: " +Math.sin(a)); // return the trigonometric cosine value of a System.out.println("Cosine value of a is: " +Math.cos(a)); // return the trigonometric tangent value of a System.out.println("Tangent value of a is: " +Math.tan(a)); // return the trigonometric arc sine of a System.out.println("Sine value of a is: " +Math.asin(a)); // return the trigonometric arc cosine value of a System.out.println("Cosine value of a is: " +Math.acos(a)); // return the trigonometric arc tangent value of a System.out.println("Tangent value of a is: " +Math.atan(a)); // return the hyperbolic sine of a System.out.println("Sine value of a is: " +Math.sinh(a)); // return the hyperbolic cosine value of a System.out.println("Cosine value of a is: " +Math.cosh(a)); // return the hyperbolic tangent value of a System.out.println("Tangent value of a is: " +Math.tanh(a)); } }
