Ruby program to find the tangent of given radian value

Program/Source Code:

The source code to find the tangent of the given radian value is given below. The given program is compiled and executed successfully.

# Ruby program to find the tangent 
# of given radian value

print "Enter value in radian: ";
radian = gets.chomp.to_f;  

result = Math.tan(radian);
print "Tangent is: ",result;

Output:

Enter value in radian: 2.123
Tangent is: -1.623004202303206

Explanation:

In the above program, we read a radian value from the user using gets.chomp.to_f and got the tangent of radian value using Math.tan() function and printed the result.
