Sin Function

Returns a Double specifying the sine of an angle.


Sin(number) The required numberargument is aDouble or any validnumeric 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.
