Then calculate the hypotenuse and the six trig functions for one of the angles of the triangle. Display all information in a Message Box. All calculations should be done using Methods. Your program should be well documented both internally and externally. Internal Documentation 3 Use of Methods Efficient coding Correctness of Program 7 Input (GUI's) Output (GUI's)

Explanation / Answer

1. Solution to first question(Triangle):

import javax.swing.JFrame;
import javax.swing.JOptionPane;

public class Triangle {

   public static void main(String[] args){
       String fl;
       fl = JOptionPane.showInputDialog("Enter First Leg of Traingle"); // input using dialog box
       int s1 =Integer.parseInt(fl);// first leg
      
       String sl;
       sl = JOptionPane.showInputDialog("Enter Second Leg of Traingle");
       int s2 =Integer.parseInt(sl);// second Leg
       double h = Math.sqrt(Math.pow(s1, 2) + Math.pow(s2, 2));// Calculating hypotenuse
      
       double degs = 90d;// right angle of traingle
       double rads = Math.toRadians(degs);//converting degrees to radians
      
       double sinA = Math.sin(rads);//sine
              
       double cosecA = 1.0/Math.sin(rads);//cosecant
      
       double cosA = Math.cos(rads);//cosine
      
       double secA = 1.0/Math.cos(rads);//secant
      
       double tanA = Math.tan(rads);//tangent
      
       double cotanA = 1.0/Math.tan(rads);//cotangent
      
       String out = "Hypotenuese is " +h + " "+
       "Trigonometric functions for right angle(90 degrees) of traingle are: "+
               " "+" " +"Sine = "+ sinA+
               " "+" " +"Cosecant = "+ cosecA+
               " "+" " +"Cosine = "+ cosA+
               " "+" " +"Secant = "+ secA+
               " "+" " +"Tangent = "+ tanA+
               " "+" " +"Cotangent = "+ cotanA;
      
      
       JOptionPane.showMessageDialog(null, out);//outputting result using message box
  
   }
}
