SQL Server - SIN() Function

The SQL Server (Transact-SQL) SIN() function returns trigonometric sine of an angle (angle should be in radians).

Syntax

SIN(x)

Parameters

`x`	`Required.` Specify the angle in radian.

Return Value

Returns the trigonometric sine of an angle.

Example 1:

The example below shows the usage of SIN() function.

SELECT SIN(0);
Result: 0

SELECT SIN(1);
Result: 0.8414709848078965

SELECT SIN(-1);
Result: -0.8414709848078965

SELECT SIN(2);
Result: 0.9092974268256817

SELECT SIN(-2);
Result: -0.9092974268256817

SELECT SIN(PI());
Result: 0.00000000000000012246467991473532

Example 2:

Consider a database table called Sample with the following records:

Data	x
Data 1	-10
Data 2	-5
Data 3	0
Data 4	5
Data 5	10

The statement given below can be used to calculate the trigonometric sine value of column x.

SELECT *, SIN(x) AS SIN_Value FROM Sample;

This will produce the result as shown below:

Data	x	SIN_Value
Data 1	-10	0.5440211108893698
Data 2	-5	0.9589242746631385
Data 3	0	0
Data 4	5	-0.9589242746631385
Data 5	10	-0.5440211108893698
