Returns a Double specifying the sine of an angle.
Sin([num]) |
The optional num argument is a Double or any valid numeric expression, specifying the angle in radians. If this argument is omitted, is a non-initialized variable, or Null, the function returns 0.
Remarks
The Sin function takes an angle in radians and returns the ratio of two sides of a right triangle. The ratio is the length of the side opposite the angle divided by the length of the hypotenuse.
The result lies in the range -1 to 1.
To convert degrees to radians, multiply degrees by pi/180. To convert radians
to degrees, multiply radians by 180/pi.
