Question

A trigonometrical expression is given as: 

`(tan "A" − tan "B")/(1 +tan "A" ∗ tan "B")`

Write a program to calculate the value of the given expression by taking the values of angles A and B (in degrees) as input.

Hint: radian = `(22/(7 ∗ 180))` ∗ degree 

Answer 1

import java.util.*; 
public class Q5 
{public static void main(String BM[]) 
{Scanner ob = new Scanner(System.in); 
double x, y, z, A = 0, B = 0, C =0, result; 
System.out.println("Enter the values of a, b, c");
A = ob.nextDouble();
B = ob.nextDouble();
C = ob.nextDouble();

//convert A, B, C from degrees to radians
A = (22.0 / (7.0 * 180.0)) * A;
B = (22.0 / (7.0 * 180.0)) * B;
C = (22.0 / (7.0 * 180.0)) * C;
result = (Math. tan(A) − Math.tan(B)) / (1 + Math.tan(A) + Math.tan(B)); 
System.out.println(result);
