SIN( ) function

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

Syntax

SIN(radians)

Parameters

radians

Numeric. The measurement of the angle in radians.

Output

Numeric.

Remarks

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

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.

Examples

Example Return value

SIN(0.523598775598299)

0.500000000000000

The return value is the sine of the specified number of radians. The radians value is equivalent to 30 degrees.

SIN(30 * PI( )/180)

0.500000000000000

The return value is the sine of 30 degrees.

DEC(SIN(30 * PI( )/180),3)

0.500

The return value is the sine of 30 degrees, rounded to 3 decimal places.
