Returns a Double specifying the sine of an angle.


Sin( number )

The required number argument is a Double or any valid numeric expression that expresses an angle in radians.


The Sin function takes an angle 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.

This example uses the Sin function to return the sine of an angle.

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