Documentation

SIN() — Returns the sine of an angle specified in radians.

SIN( {numeric-expression} )

The SIN() function returns the sine of a specified angle as a FLOAT value. The angle must be specified in radians as a numeric expression.

The following example returns the sine, cosine, and tangent of angles from 0 to 90 degrees (where the angle is specified in radians).

SELECT SIN(radians), COS(radians), TAN(radians) 
     FROM triangles WHERE radians >= 0 AND radians <= PI()/2;
