Ruby | Math sin() function

The sin() is an inbuilt function in Ruby returns the sine of a given angle expressed in radians which is in range [-inf, +inf]. The returned value is in range [-1, +1].

Syntax: Math.sin(value) 

Parameters: The function accepts one mandatory parameter value whose corresponding sine is returned. 

Return Value: It returns the sine.

Example 1: 

Ruby

#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)

Output: 

 0.07075223608034517
1.0
-0.25408576770942626
-0.8600694058124533

Example 2: 

Ruby

#Ruby program for sin() function

#Assigning values
val1 = 1 val2 = 0 val3 = 989 val4 = -8932

#Prints the sin() value
                                     puts Math.sin(val1)
                                         puts Math.sin(val2)
                                             puts Math.sin(val3)
                                                 puts Math.sin(val4)

Output: 

0.8414709848078965
0.0
