SIN( ) function

Returns the sine of an angle expressed in radians, with a precision of 15 decimal places.

Syntax

SIN(radians)

Parameters

Name	Type	Description
radians	numeric	The measurement of the angle in radians.

Output

Numeric.

Examples

Basic examples

Returns 0.500000000000000 (the sine of the specified number of radians, equivalent to 30 degrees):

SIN(0.523598775598299)

Returns 0.500000000000000 (the sine value of 30 degrees):

SIN(30 * PI( )/180)

Advanced examples

Using degrees as input

Returns 0.500 (the sine of 30 degrees, rounded to 3 decimal places):

DEC(SIN(30 * PI( )/180),3)

Remarks

Performing the Mantissa Arc Test

The three trigonometric functions in Analytics – SIN( ), COS( ), and TAN( ) – support performing the Mantissa Arc Test associated with Benford's Law.

Converting degrees to radians

If your input is in degrees you can use the PI( ) function to convert the input to radians: (degrees * PI( )/180) = radians. If required, you can round or truncate the return value using the DEC( ) function.
