Ruby | Math sin() function

The cos() 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.cos(value)

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

Return Value: It returns the sine.

Example 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) `

Output:

``` 0.07075223608034517
1.0
-0.25408576770942626
-0.8600694058124533
```

Example 2:

 `#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
0.5660330877786267
0.43684277891924755
