SIN DAX Function (Math and Trig)
Returns the sine of the given angle.
Syntax
SIN ( <Number> )
| Parameter | Attributes | Description |
|---|---|---|
| Number |
The angle in radians for which you want the sine. |
Return values
Scalar A single decimal value.
Returns the sine of the given angle.
Remarks
If your argument is in degrees, multiply it by PI()/180 or use the RADIANS function to convert it to radians.
Examples
-- SIN, COS, ASIN, ACOS, TAN, ATAN, COT, ACOT are the
-- standard trigonometrical functions.
--
-- Where required, the arguments are specified in radians.
