Calculating hyperbolic functions

[Java Tip]

import java.lang.*;

class HypFun
{
public static void main(String[] args)
{
     double rads, degs, sinHA, cosHA, tanHA, asinHA;

     // Obtain angle in degrees from user   
     degs = 20d;
     // Convert degrees to radian        
     rads = Math.toRadians(degs);

     // Calculate hyperbolic sine
     sinHA = (Math.exp(rads) - Math.exp(-rads))/2;
     System.out.println("Hyperbolic sine = "  + sinHA); 
     // Calculate Hyperbolic cosine 
     cosHA = (Math.exp(rads) + Math.exp(-rads))/2;
     System.out.println("Hyperbolic cosine = "  + cosHA);

     // Calculate hyperbolic tangent
     tanHA = sinHA/ cosHA;
     System.out.println("Hyperbolic tangent = " + tanHA);

     // Calculate hyperbolic arc-sine 
     asinHA = Math.log(sinHA + Math.sqrt((sinHA * sinHA)+ 1.0));
     degs = Math.toDegrees(asinHA);
     System.out.println("Arc hyperbolic sine = " + degs);
