Program/Source Code:

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

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

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

result = Math.sin(radian);
print "Sine is: ",result;

Output:

Enter value in radian: 2.12
Sine is: 0.8529404815528762

Explanation:

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