Sin Function

Returns a Double specifying the sine of an angle.

Syntax

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.

Example

Dim MyAngle, MyCosecant
MyAngle = 1.3   ' Define angle in radians.
MyCosecant = 1 / Sin(MyAngle)   ' Calculate cosecant.
