# Ruby | BigDecimal sin() function

BigDecimal#sin() : sin() is a BigDecimal class method which returns the sine of decimal to the specified number of digits of precision, numeric.

Syntax: BigDecimal.sin()

Parameter: BigDecimal values

Return: the sine of decimal to the specified number of digits of precision, numeric.

Example #1 :

 `# Ruby code for BigDecimal.sin() method ` ` `  `# loading library ` `require ``'bigdecimal'` ` `  `# declaring bigdecimal ` `a = BigDecimal(``"10"``) ` ` `  `# declaring bigdecimal ` `b = BigDecimal(``"1000"``) *``2` ` `  `# declaring bigdecimal ` `c = BigDecimal(``"11.43"``) ` ` `  `# sin() method ` `puts ``"BigDecimal a sin method : #{Math.sin(a)}\n\n"` ` `  `puts ``"BigDecimal b sin method : #{Math.sin(b)}\n\n"` ` `  `puts ``"BigDecimal a sin method : #{Math.sin(c)}\n\n"`

Output :

```BigDecimal a sin method : -0.5440211108893698

BigDecimal b sin method : 0.930039504416137

BigDecimal a sin method : -0.9071119034933154

```

Example #2 :

 `# Ruby code for BigDecimal.sin() method ` ` `  `# loading library ` `require ``'bigdecimal'` ` `  `# declaring bigdecimal ` `a = BigDecimal(``'12'``)*``12` ` `  `# declaring bigdecimal ` `b = BigDecimal(``'10'``)+(``22` `** ``7``.``1``) ** ``10` ` `  `# declaring bigdecimal ` `c = -BigDecimal(``'-3'``) ` ` `  `# sin() method ` `puts ``"BigDecimal a sin method : #{Math.sin(a)}\n\n"` ` `  `puts ``"BigDecimal b sin method : #{Math.sin(b)}\n\n"` ` `  `puts ``"BigDecimal a sin method : #{Math.sin(c)}\n\n"`

Output :

```BigDecimal a sin method : -0.49102159389846933

BigDecimal b sin method : 0.9772308602356717

BigDecimal a sin method : 0.1411200080598672
