SIN Function Details
 
Syntax
  SIN(numeric-expression)
 
The SIN function is calculated with double-precision accuracy when x is a
double-precision value. When x is not double precision, SIN is calculated
with single-precision accuracy.
 
You can convert an angle measurement from degrees to radians by
multiplying the degrees by π/180, where π = 3.141593.
 
To convert a radian value to degrees, multiply it by 57.2958.
