# SIN Function

#### Purpose:

To calculate the trigonometric sine of *x*, in radians.

#### Syntax:

**SIN**(*x*)

#### Comments:

SIN(*x*) is calculated in single-precision unless the /**d** switch is used when GW-BASIC is executed.

To obtain SIN(*x*) when *x** *is in degrees, use SIN(x*π/180).

#### Examples:

PRINT SIN(1.5)
.9974951

The sine of 1.5 radians is .9974951 (single-precision).
