Syntax
COS(radians)
Parameters
| Name | Type | Description |
|---|---|---|
| radians | numeric | The measurement of the angle in radians. |
Output
Numeric.
Examples
Basic examples
Returns 0.500000000000000 (the specified number of radians):
COS(1.047197551196598)
Advanced examples
Using degrees as input
Returns 0.500000000000000 (the cosine of 60 degrees):
COS(60 * PI( )/180)
Rounding to 3 decimal places
Returns 0.500 (the cosine of 60 degrees, rounded to 3 decimal places):
DEC(COS(60 * 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.
