例子1：

#Ruby program for sin() function 
  
#Assigning values 
val1 = 176 val2 = Math::PI / 2 val3 = -3123 val4 = -89 
  
#Prints the sin() value 
                                                    puts Math.sin(val1) 
                                                        puts Math.sin(val2) 
                                                            puts Math.sin(val3) 
                                                                puts Math.sin(val4)
